Abstract

International audience; A high statistics ∑p scattering experiment has been performed at the K1.8 beamline in the J-PARC Hadron Experimental Facility. Data for momentum-tagged ∑− beam running in a liquid hydrogen target were accumulated by detecting the reaction with a high intensity π− beam of 20 M/spill. The number of the Σ− beam was about 1.7 × 107 in total. The ∑−ρ elastic scattering and the ∑−p → Λn inelastic scattering events were successfully observed with about 100 times larger statistics than that in past experiments.

158. Self-organized Ge clustering on partially Ga-terminated Si(111) surfaces

Author

Subjects

Abstract

Researchers investigated the growth of germanium (Ge) on partially gallium-terminated Si(111) substrates. They demonstrated that Ge growth causes redistribution of Ga into condensed and exhausted areas, and that this pattern influences the succeeding growth of Ge. The Ge continues to grow in layer-by-layer mode in the Ga-condensed areas and in Stranski-Krastanov mode in the other areas. The controlling influence is on alignment of Ge clusters rather than size of clusters.

159. Observation of selective thermal desorption of electron stimulated SiO2 with a combined scanning reflection electron microscope/scanning tunneling microscope

Abstract

A combined scanning reflection electron microscope/scanning tunneling microscope was employed in analyzing the selective thermal desorption (STD) of electron stimulated SiO2 films less than 1 nm thick. Results show that STD-formed clean Si open windows have uniform linewidth and atomically flat surface morphology. The surface morphology was also found to be dependent on desorption temperature, oxide film thickness and electron dose.

Abstract

A study was conducted on high temperature superconducting (HTS) fault current limiters (FCLs) for electric power system applications. A magnetic shielding type FCL consisting of a superconducting cylinder, iron core, control coil and a copper primary winding was developed. The superconducting cylinder employs a Bi-2212 thick film on a MgO substrate while the control coil is made up of metallic rings.

168. Radiative depopulation of the excited intramolecular charge-transfer state of 9-(4-N,N-dimethylaminophenyl)phenanthrene

Abstract

The solvent dependence of the spectral position of the charge-transfer fluorescence maxima, quantum yield, excited state depopulation kinetics and resulting radiative rate constant are investigated. Single photon timing and picosecond transient absorption experiments in a polar and an apolar solvent are performed to get more information about the fluorescent excited states. Results indicate that emission occurs from a highly polar excited state and that the high quantum yield increases as solvent polarity increases. Moreover, solvents of intermediate polarity show a maximum radiative rate constant.

Abstract

Laser absorption analysis of particle number densities of Xe+* and He*, the excited components, is possible with a continuous wave dye laser which revealed that the main reaction of the formation of XeCl* is the three-body ion-ion recombination. This recombination is observed in transversal discharge excimer lasers of XeCl. Low Xe+* ion densities do not determine the output energy of the low specific laser of the longitudinal discharge laser.

Abstract

Modifications were made on a conventional transmission electron microscope operating with a cold field emission source to allow differential phase contrast mapping and observations of microscopic magnetic characteristics. Tests have shown that the Lorentz electron microscope is capable of providing information on the details of bits recorded on longitudinal recording media. In addition, it was useful for studying the effect of delineated bit profiles on device performance.

Abstract

Bound systems of |$\Xi^-$| – |$^{14}_{}{\rm N}$| are studied via |$\Xi^-$| capture at rest followed by emission of a twin single- |$\Lambda$| hypernucleus in the emulsion detectors. Two events forming extremely deep |$\Xi^-$| bound states were obtained by analysis of a hybrid method in the E07 experiment at J-PARC and reanalysis of the E373 experiment at KEK-PS. The decay mode of one event was assigned as |$\Xi^-+^{14}\!\,\!\!{\rm N}\to^{5}_{\Lambda}\!\!\!{\rm He} + ^{5}_{\Lambda}\!\!{\rm He} + ^{4}\!\!{\rm He} + \mathrm{n}$|⁠. Since there are no excited states for daughter particles, the binding energy of the |$\Xi^-$| hyperon, |$B_{\Xi^-}$|⁠ , in the |$^{14}_{}{\rm N}$| nucleus was uniquely determined to be |$6.27 \pm 0.27$| MeV. Another |$\Xi^-$| – |$^{14}_{}{\rm N}$| system via the decay |$^{9}_{\Lambda}{\rm Be} + ^{5}_{\Lambda}\!\!\!{\rm He} + \mathrm{n}$| brings a |$B_{\Xi^-}$| value, |$8.00 \pm 0.77$| MeV or |$4.96 \pm 0.77$| MeV, where the two possible values of |$B_{\Xi^-}$| correspond to the ground and the excited states of the daughter |$^{9}_{\Lambda}{\rm Be}$| nucleus, respectively. Because the |$B_{\Xi^-}$| values are larger than those of the previously reported events (KISO and IBUKI), which are both interpreted as the nuclear |$1p$| state of the |$\Xi^-$| – |$^{14}_{}{\rm N}$| system, these new events give the first indication of the nuclear |$1s$| state of the |$\Xi$| hypernucleus, |$^{15}_{\Xi}{\rm C}$|⁠.
