Abstract: Application of a clover Ge detector to the measurement of the linear polarization of β -delayed γ rays was investigated. The spectrometer consists of the clover and coaxial-type Ge detectors, and will be installed at an on-line isotope separator to measure short-lived nuclei. To evaluate the performance of the spectrometer, the polarization sensitivities were determined using standard radioactive sources in various detector arrangements. During optimization of the detector setup, the figure of merit was found to depend on the solid angles subtended by the detectors.

Abstract: The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) offers the unique capability to collide polarized protons at high energies. One of the highlights of the polarized proton program performed at s = 500 GeV is that it affords the direct measurement of sea quark contribution to the proton spin via W-boson production through the measurement of the parity violating single spin asymmetry. A new trigger electronics system for forward muons, which is especially capable of W-boson detection, was developed for the PHENIX experiment. The trigger was installed as an additional electronic circuit, and it was connected in parallel with the existing cathode readout electronics of the muon tracking chamber.

Abstract: We report measurements of differential cross sections and decay asymmetries of incoherent ϕ-meson photoproduction from the deuteron at forward angles using linearly polarized photons at E γ = 1.5 – 2.4 GeV . The nuclear transparency ratio for the deuteron shows a large suppression, and is consistent with the A-dependence of the ratio observed in a previous measurement with nuclear targets. The reduction for the deuteron cannot be adequately explained in term of isospin asymmetry. The present results suggest the need of refining our understanding of the ϕ–N interaction within a nucleus.

Abstract: We present the first measurement of photoproduction of J/psi and of two-photon production of high-mass e(+)e(-) pairs in electromagnetic (or ultra-peripheral) nucleus-nucleus interactions, using Au + Au data at root s(NN) = 200 GeV. The events are tagged with forward neutrons emitted following Coulomb excitation of one or both Au* nuclei. The event sample consists of 28 events with m(e+e-) > 2 GeV/c(2) with zero like-sign background. The measured cross sections at midrapidity of d sigma/dy (J/psi + Xn, y = 0) = 76 +/- 33 (stat) +/- 11 (syst) pb and d(2)sigma /dm dy (e(+) e(-) + Xn, y = 0) = 86 +/- 23(stat) +/- 16(syst) mu b/ (GeV/c(2)) for m(e+e-) epsilon vertical bar 2.0, 2.8 vertical bar GeV/c(2) have been compared and found to be consistent with models for photoproduction of J/psi and QED based calculations of two-photon production of e(+)e(-) pairs.

Abstract: PHENIX has measured the electron-positron pair mass spectrum from 0 to 8 GeV/c(2) in p + p collisions at root s = 200 GeV. The contributions from light meson decays to e(+)e(-) pairs have been determined based on measurements of hadron production cross sections by PHENIX. Within the systematic uncertainty of similar to 20% they account for all e(+)e(-) pairs in the mass region below similar to 1 GeV/c(2). The e(+)e(-) pair yield remaining after subtracting these contributions is dominated by semileptonic decays of charmed hadrons correlated through flavor conservation. Using the spectral shape predicted by PYTHIA, we estimate the charm production cross section to be 544 +/- 39(stat) +/- 142(syst) +/- 200(model) pb. which is consistent with QCD calculations and measurements of single leptons by PHENIX.

Abstract: Differential cross sections and decay asymmetries for coherent $\phi$-meson photoproduction from deuterons were measured for the first time at forward angles using linearly polarized photons at $E_{\gamma}$= 1.5-2.4 GeV. This reaction offers a unique way to directly access natural-parity Pomeron dynamics and gluon exchange at low energies. The cross sections at zero degrees increase with increasing photon energy. The decay asymmetries demonstrate a complete dominance of natural-parity exchange processes, showing that isovector unnatural-parity $\pi$-meson exchange is small. Nevertheless the deduced cross sections of $\phi$-mesons from nucleons contributed by isoscalar t-channel exchange processes are not well described by the conventional Pomeron model., Comment: 14 pages, 6 figures.

Abstract: Summary Background We had previously developed the possibility of use of a photodynamic diagnosis (PDD) system using a tumor-selective photosensitizer and laser irradiation for the early detection and photodynamic therapy (PDT) for centrally located early lung cancers. Recently, we established the autofluorescence diagnosis system integrated into a videoendoscope (SAFE-3000) as a very useful technique for the early diagnosis of lung cancer. Patients and methods Twenty-nine patients (38 lesions) with centrally located early lung cancer received PDD and PDT using the second-generation photosensitizer, talaporfin sodium (NPe6). Just before the PDT, we defined the tumor margin accurately using the novel PDD system SAFE-3000 with NPe6 and a diode laser (408 nm). Results Red fluorescence emitted from the tumor by excitation of the photosensitizer by the diode laser (408 nm) from SAFE-3000 allowed accurate determination of the tumor margin just before the PDT. The complete remission (CR) rate following NPe6-PDT in the cases with early lung cancer was 92.1% (35/38 lesions). We also confirmed the loss of red fluorescence from the tumors immediately after the PDT using SAFE-3000. We confirmed that all the NPe6 in the tumor had been excited and photobleached by the laser irradiation (664 nm) and that no additional laser irradiation was needed for curative treatment. Conclusions This novel PDD system using SAFE-3000 and NPe6 improved the quality and efficacy of PDT and avoided misjudgement of the dose of the photosensitizer or laser irradiation in PDT. PDT using NPe6 will become a standard option of treatments for centrally located early lung cancer.

Abstract: Differential cross sections and photon beam asymmetries for π 0 photoproduction have been measured at E γ = 1.5 – 2.4 GeV and at the π 0 scattering angles, − 1 cos Θ c . m . − 0.6 . The energy-dependence of differential cross sections for u-channel π 0 production has been determined. An enhancement at backward angles is found above E γ = 1.9 GeV . This is likely to be due to u-channel diagrams. Photon beam asymmetries have been obtained for the first time at backward angles, showing a strong angular dependence at E γ > 2.0 GeV .

Abstract: Development of acquired resistance to gefitinib after an initial good response is common. Recently, it was reported that this acquired resistance is related to a secondary mutation associated with a substitution of threonine by methionine at codon 790 (T790M) of the epidermal growth factor receptor (EGFR) gene. In this report, we present a "never smoking" woman with advanced lung cancer who showed acquired resistance to gefitinib, and analysis of autopsy samples revealed no evidence of EGFR mutations in either exons 18-21 or codon 790, and positive immunostaining for breast cancer resistance protein (BCRP). We describe, for the first time, a case in which expression of BCRP was associated with acquired resistance to gefitinib, independent of EGFR mutations.

Abstract: In the 2001–2002 running period of the Relativistic Heavy Ion Collider (RHIC), transversely polarized protons were accelerated to 100 GeV for the first time, with collisions at s = 200 GeV . We present results from this run for single transverse-spin asymmetries for inclusive production of neutral pions, photons and neutrons of the energy region 20–100 GeV for forward and backward production for angles between 0.3 mrad and 2.2 mrad with respect to the polarized proton direction. An asymmetry of A N = ( − 0.090 ± 0.006 ± 0.009 ) × ( 1.0 −0.24 +0.47 ) was observed for forward neutron production, where the errors are statistical and systematic, and the scale error is from the beam polarization uncertainty. The forward photon and π 0 , and backward neutron, photon, and π 0 asymmetries were consistent with zero. The large neutron asymmetry indicates a strong interference between a spin–flip amplitude, such as one pion exchange which dominates lower energy neutron production, and remaining spin–non-flip amplitudes such as reggeon exchange.

Abstract: Correlations between p and (p) over bar at transverse momenta typical of enhanced baryon production in Au + Au collisions are reported. The PHENIX experiment has measured same and opposite sign baryon pairs in Au + Au collisions at root s(NN) = 200 GeV. Correlated production of p and p with the trigger particle from the range 2.5 < p(T) < 4.0 GeV/c and the associated particle with 1.8 < p(T) < 2.5 GeV/c is observed to be nearly independent of the centrality of the collisions. Same sign pairs show no correlation at any centrality. The conditional yield of mesons triggered by baryons (and anti-baryons) and mesons in the same p(T) range rises with increasing centrality, except for the most central collisions, where baryons show a significantly smaller number of associated mesons. These data are consistent with a picture in which hard scattered partons produce correlated p and (p) over bar in the p(T) region of the baryon excess. (c) 2007 Elsevier B.V. All rights reserved.

Abstract: The photoluminescence (PL) profiles in deep region of ZnTe grown on tilted GaAs (0 0 1) substrates, 2° off toward 〈1 1 0〉, without ZnSe buffer layer have weak self-activated (SA) emissions at about 1.6–2.0 eV. PL shows the characteristic dependence on the excitation intensity and temperature. The excitation intensity dependence of the PL structure at 2.322 eV shows that the emission structure is due to the donor–acceptor pairs (DAP). The temperature dependence of the DAP emission indicates a two-step thermal quenching process. The zero-phonon line of the phonon replicas of oxygen isoelectronic traps is lowered by 5 meV from that of bulk crystal due to the difference in the thermal expansions between ZnTe and the substrate. The emissions at around 1.65 eV are the SA emissions related to Te-interstitial atoms.

Abstract: The specially designed ZnSe–ZnTe superlattice (SL), type-II SL, has the light up-conversion effect that SL emits a photoluminescence (PL) peak under the irradiation of the excitation light with the lower energy than the PL peak. The excitation intensity dependence of the energy of up-converted PL peak obeys the characteristic of type-II SL. The PL peak intensity has the super-linear dependence on the excitation intensity. The five kinds of samples in this work showed these phenomena. The model to explain these situations has been proposed.

Abstract: Human β-defensins (hBDs) are the most abundant antimicrobial peptides in epithelial cells, and function in the host immune system. Respiratory epithelial cells express hBDs to inhibit bacterial proliferation during respiratory tract infections. The aim of this study was to investigate the release of hBDs into the respiratory tract and their benefit as a host defence system in chronic Pseudomonas aeruginosa infections. The levels of four hBD peptides (hBD-1–hBD-4) were measured in the bronchial epithelial lining fluid (ELF) of nine patients with chronic lower respiratory tract infection caused by P. aeruginosa. Eight patients with idiopathic pulmonary fibrosis and eight volunteers free of pulmonary disease were recruited as controls. ELF was obtained by bronchoscopic microsampling and hBD levels were measured by radioimmunoassays. The antimicrobial effects of hBDs were studied individually and in combination using an in-vitro colony count assay for P. aeruginosa. Concentrations of hBD-1 and hBD-3 tended to be higher in patients with chronic lower respiratory tract infection than in the controls. hBD-2 and hBD-4 were detected in ELF from five and four of nine patients, respectively, but the hBD levels in controls were all below the limits of detection. All patients with infection caused by mucoid P. aeruginosa had detectable hBD-2 and hBD-4 levels in ELF. In-vitro colony count assays showed a potential synergism between hBD-2 and hBD-4 in inhibiting bacterial proliferation. The findings indicate that hBDs, especially hBD-2 and hBD-4, are pathophysiologically important in infections caused by mucoid strains of P. aeruginosa.

Abstract: We have searched for Θ + via π − p → K − X reaction using 1.87 and 1.92 GeV / c π − beam at the K2 beam line of the KEK 12 GeV proton synchrotron. In the missing mass spectrum at beam momentum of 1.92 GeV / c , a bump has been found at 1530 MeV / c 2 which is consistent with the mass reported by several experiments. The statistical significance of this bump, however, is only 2.5 – 2.7 σ . Therefore we have derived the upper limit of Θ + production cross section via π − p → K − Θ + reaction which is 3.9 μb at 90% confidence level assuming that Θ + is produced isotropically in the center of mass system.

Abstract: A hyperon–nucleon scattering experiment, KEK-PS E289, was carried out at the K2 beam line in KEK. We adopted a scintillating fiber active target as a hydrogen target for hyperon production and subsequent hyperon–nucleon scattering. We collected more data than in a previous experiment, KEK-PS E251. In this paper, the differential cross sections for Σ+p elastic scattering in the incident momentum range from 350 to 750 MeV/c are presented and compared with theoretical predictions from the Nijmegen group (Nijmegen Soft Core 97) and the Kyoto–Niigata group (RGM-FSS and fss2).

Abstract: We observed two γ-ray transitions of 16ΛO in the 16O( K − , π − γ ) reaction using a germanium detector array, Hyperball. The γ rays are assigned as the M1 transitions from the 6 MeV excited state ( 1 − ) to the ground state doublet ( 1 − , 0 − ). The energies of the γ rays are 6534.1 ± 1.5 keV and 6560.2 ± 1.3 keV , and the energy spacing is 26.1 ± 2.0 keV , which corresponds to the ground state doublet spacing. From their yield ratio of 0.65 ± 0.11 ( N ( 6534 ) / N ( 6560 ) ) , the spin order of the ground state doublet is determined. This result gives a small value for the ΛN tensor force strength.

Abstract: We have performed a γ spectroscopy experiment in 11 Λ B using a germanium detector array, Hyperball. In this experiment, we have observed six γ transitions from 11 Λ B. Among these transitions, the γ ray peak at 1482 keV is identified as E2 ( 1 / 2 + → 5 / 2 + ) . The result of this experiment indicates that the level structure seems quite different from a theoretical prediction based on the results of the previous experiments.

Abstract: We performed an experiment to measure γ rays of hyperfragments produced by stopped K − reactions on light ( A ⩽ 12 ) targets (KEK-PS E509). We clearly observed an E2 transition ( 5 / 2 + → 1 / 2 + ) in 7ΛLi with 10B, 11B and 12C targets and obtained the γ-ray intensity to be ( 7.5 ± 1.6 ) × 10 −4 per stopped K − for 10B target. In addition, a candidate for a new hypernuclear γ ray was observed. These results show that this method is quite suitable for the systematic study of hypernuclei.

Abstract: The present status of hypernuclear gamma-ray spectroscopy with Hyperball is summarized. We observed two gamma transitions of 16-Lambda-O(1- -> 1-,0-) and obtained the strength of the Lambda-N tensor force. In 10B(K-,pi- gamma) data, we did not observe the spin-flip M1 transition of 10-Lambda-B(2- -> 1-), but gamma rays from hyperfragments such as 7-Lambda-Li(7/2+ -> 5/2+) and 9-Lambda-Be(3/2+ ->1/2+) were observed. In 11B(pi+,K+ gamma) data, we observed six gamma transitions of 11_Lambda-B. We also attempted an inclusive gamma-ray measurement with stopped K- beam.

Abstract: The photoluminescence (PL) spectra of the type II ZnSe–ZnTe superlattices with dual-subband structures have two emission peaks. The PL peak at the higher energy side appears by the excitation even with the light, with the middle energy between the PL peaks. The emission energy of the up-converted light shows dependence similar to the case of direct excitation (high-energy excitation) on the excitation intensity. The emission energy increases with increase in the excitation intensity. The up-converted and the direct excited emissions are due to the same state in the superlattice.

Abstract: Photon beam asymmetries for the γ → p → K + Λ and γ → p → K + Σ 0 reactions have been measured for the photon energy range from 1.5 GeV to 2.4 GeV and for the angular range of 0 ° Θ cm K + 60 ° at the SPring-8/LEPS facility. The observed asymmetries are found to be positive and increase with increasing the photon energy. Present theoretical calculations do not reproduce the data. To extend our knowledge on the K + photoproduction mechanism including the effect of nucleon resonances, further theoretical development is required to fit both the cross section and asymmetry data.

Abstract: The photo-production of ϕ mesons from Li, C, Al, and Cu at forward angles has been measured at E γ = 1.5 – 2.4 GeV . The number of events for incoherent ϕ photo-production is found to have a target mass number dependence of A 0.72 ± 0.07 in the kinematical region of | t | ⩽ 0.6 GeV 2 / c 2 . The total cross section of the ϕ –nucleon interaction, σ ϕ N , has been estimated as 35 −11 +17 mb using the A -dependence of the ϕ photo-production yield and a Glauber-type multiple scattering theory. This value is much larger than σ ϕ N in free space, suggesting that the ϕ properties might change in the nuclear medium.

Abstract: A position sensing microprobe has been developed which satisfies harsh requirements to establish a nano-CMM (coordinate measuring machine) proposed for measuring microparts with a target accuracy of less than 50 nm within a 10 mm cubed working volume. This paper deals with dynamic properties and position sensing accuracy of the improved microprobe system for the nano-CMM using an optically trapped probe sphere of 8.0 ^m in diameter. The probe sphere is forced to vibrate with about a hundred nanometer amplitude and high frequency based on optical radiation pressure control. It is possible to measure its dynamic motions with a higher accuracy using the newly developed optical system with a position sensing detector (PSD). It is experimentally suggested that the improved microprobe system can achieve nano-position sensing in the lateral direction.

Abstract: We have developed three kinds of phosphor/neutron-converter scintillators aiming to increase the detection efficiency of the neutron imaging detectors. One is the ZnS:Ag/ 6 LiF (powder) scintillator, which contained 6 LiF about twice in amount comparing to the commercial product (Bicron, BC-704) and painted in a sheet, and the 0.4-mm-thick scintillator sheet exhibited the detection efficiency of 43.5% for thermal neutrons. This value was improved ∼1.5 times than that of BC-704. Another developed scintillator was a ZnS:Ag/ 10 B 2 O 3 (powder), which contained 10 B as a neutron converter. The scintillator was fabricated by sintering up to the temperature of 500 or 600°C, and it exhibited the detection efficiency of 30% for thermal neutrons. Moreover, we developed ZnS:Ag/ 10 B 2 O 3 glass-scintillator, which was fabricated by increasing the amount of 10 B 2 O 3 up to 70–90% of the constituents and by sintering the scintillator materials up to the temperature of 650°C. The fabricated glass scintillators, which had a thickness of 0.9–1 mm, exhibited the detection efficiency of 20–40% for thermal neutrons.

Abstract: A microprobe system with a micrometer size probe sphere is required to establish the nano-CMM that is a three dimensional coordinate measuring machine with a measuring range of mm and accuracy of nm order. In this paper, the newly developed vibrational probing technique for the microprobe sytem is presented. The principle is based on the single-beam gradient-force optical trap and the forced vibration method. An optically trapped silica particle in air is vibrated using the laser beam scanning method. Frequency response is examined to estimate the radial spring constant of the microprobe system. Fundamental measurements of a micro-step specimen fabricated using a FIB (Focused Ion Beam) process are demonstrated to investigate the position detection sensitivity.

Abstract: Using a large-acceptance germanium detector array (Hyperball), we measured a γ -ray spectrum in coincidence with production of 7 Λ Li bound states in the 7 Li( π + , K + ) reaction. We observed a γ -ray peak at 429 keV due to the transition from the first excited state of 7 Be produced by the weak decay of 7 Λ Li, 7 Λ Li → 7 Be ∗ (1/2 − ,429 keV )+π − . From the yield of this γ -ray, the branching ratio of the 7 Λ Li weak decay to 7 Be ∗ (429) was obtained to be (6.0 +1.3 −1.6 )×10 −2 . Compared with theoretically calculated values of the partial decay rates, the measurement indicates that the ground-state spin of 7 Λ Li is 1/2 but not 3/2.

Abstract: We have constructed a Time Projection Chamber (TPC) as the 4π detector for hadron photoproduction experiments at SPring-8. A feature of this TPC is to detect low momentum hyperons as close as 16 mm from the target center. We have studied basic performances of the TPC such as the resolution of dE / dx measurement and the spatial resolution with cosmic rays. The resolution of dE / dx measurement is 16% for minimum ionizing particles. The spatial resolution in pad plane is 280 μm and that along drift direction is 620 μm. The spatial resolution at the distance of 16 mm from the target is obtained to be 400 μm and 880 μm in pad plane and along drift direction respectively.

Abstract: In addition to heavy ion collisions (RHIC Design Manual, Brookhaven National Laboratory), RHIC will also collide intense beams of polarized protons (I. Alekseev, et al., Design Manual Polarized Proton Collider at RHIC, Brookhaven National Laboratory, 1998 [2]), reaching transverse energies where the protons scatter as beams of polarized quarks and gluons. The study of high energy polarized protons beams has been a long term part of the program at BNL with the development of polarized beams in the Booster and AGS rings for fixed target experiments. We have extended this capability to the RHIC machine. In this paper we describe the design and methods for achieving collisions of both longitudinal and transverse polarized protons in RHIC at energies up to s =500 GeV .

Abstract: The PHENIX Muon Arms detect muons at rapidities of | y |=(1.2–2.4) with full azimuthal acceptance. Each muon arm must track and identify muons and provide good rejection of pions and kaons (∼10 −3 ). In order to accomplish this we employ a radial field magnetic spectrometer with precision tracking (Muon Tracker) followed by a stack of absorber/low resolution tracking layers (Muon Identifier). The design, construction, testing and expected run parameters of both the muon tracker and the muon identifier are described.
