F.Z. received support from the Research Council of Norway under Contract No. 263030., We report on spectroscopic information and lifetime measurements of even-even neutron-rich Te isotopes. Excited states were populated in fast-neutron induced fission of U-238 at the ALTO facility of IJCLab with the LICORNE neutron source and detected using the hybrid.-ball spectrometer. We provide first results on lifetimes of the 6(1)(+) state in Te-136 and the (6(1)(+)), (4(1)(+)), and (2(1)(+)) states in Te-138 and discuss the results in the context of large-scale shell-model calculations. The level schemes of Te-136 and Te-138 are revised in terms of lifetimes of their 2(1)(+), 4(1)(+) states and updated information on the (4(2)(+)) state in Te-136 is presented. In addition, previously reported data on spectroscopy and lifetimes in Te-134 are reexamined.

- Abstract
Welding fumes have been found to be carcinogenic and stainless steel welders may be at higher risk due to increased formation of hexavalent chromium (Cr(VI)). The slag-shielded methods, identified to generate most airborne particles and Cr(VI), would potentially be most harmful. With ever-stricter limits set to protect workers, measures to minimize human exposure become crucial. Austenitic stainless steel flux-cored wires of 316L type have been developed with the aim to reduce the toxicity of the welding fume without compromised usability. Collected particles were compared with fumes formed using solid, metal-cored, and standard flux-cored wires. In part 1, the new wires were concluded to have improved weldability, to generate even less Cr(VI) in wt.-% than with solid wire and to be less acute toxic in cultured human bronchial epithelial cells as compared to standard flux-cored wires. In part 2, two additional institutes created fume emission datasheets for the same wires for correlation with the fume data obtained in part 1. The reported values showed large variations between the three laboratories, having a significant effect on the standard deviation. This is suggested to be the result of different welding parameters and various ways to collect and analyze the fume. More stringent specifications on parameter settings and fume collection would be required to increase the accuracy. This means that at present, it may not be possible to compare fume data on datasheets from two different wire producers and care should be taken in interpretation of values given in the available literature. Nevertheless, the laboratories confirmed the same trends for Cr(VI) as presented in part 1., QC 20220523

Gamma-ray images of VVER-440 and SVEA-96 spent nuclear fuel assemblies were reconstructed using the filtered backprojection algorithm from measurements with a passive gamma emission tomography prototype instrument at Finnish nuclear power plants. Image quality evaluation criteria based on line profiles through the reconstructed image are used to evaluate image quality for spent fuel assemblies with different cooling times, and thus different mixtures of gamma-ray emitting isotopes. Image characteristics at the locations of water channels and central fuel pins are compared in two gamma-ray energy windows, 600-700 and >700keV, for cooling times up to 10 years for SVEA-96 fuel and 24.5 years for VVER-440 fuel. For SVEA-96 fuel, images in the >700-keV gamma-ray energy window present better water-to-fuel contrast for all investigated cooling times. For VVER-440, images in the >700-keV gamma-ray energy window have higher water-to-fuel contrast up to and including a cooling time of 18.5 years, whereas the water-to-fuel contrast of the images taken in the two gamma-ray energy windows is equivalent for a cooling time of 24.5 years. Images reconstructed from higher energy gamma rays such as those in the >700-keV energy window present better water-to-fuel contrast in fuel cooled for up to 20 years and thus have the most potential for missing fuel pin detection.

Natural gadolinium displays a number of remarkable physical properties: it is a rare earth element, composed of seven stable or quasi-stable isotopes, with an exceptionally high magnetization and a Curie point near room temperature. Its use in the field of nuclear instrumentation historically relates to its efficiency as a neutron poison in power reactors. Gadolinium is indeed the naturally occurring element with the highest interaction probability with neutrons at thermal energy, shared between Gd-157 (15.65%, 254000 b cross section) and Gd-155 (14.8%, 60900 b) isotopes. Considering that neutron capture results in an isotopic change, followed by a radiative rearrangement of nuclear and atomic structures, Gd may be embodied not merely as a neutron poison but as a neutron converter into a prompt photon and an electron source term. Depending on the nature and energy of the reaction products (from a few-keV Auger electrons up to 8 MeV gamma rays) that the detector aims at isolating as an indirect neutron signature, a variety of sensor media and counting methods have been introduced during the last decades. This review first draws a theoretical description of the radiative cascade following Gd ( n , γ ) capture. The cascade may be subdivided into regions of interest, each corresponding to dedicated detection designs and optimizations whose current status is detailed. This inventory has allowed the authors to extract and benchmark key figures of merit for the definition of a detection scheme: neutron attenuation, neutron sensitivity (cps/nv), gamma rejection, neutron detection limit in a mixed field, intrinsic or extrinsic moderation, and transportability. On this basis, the authors have identified promising paths for Gd-based neutron detection in contemporary instrumentation.

The spectroscopic quadrupole moments of the 11(-) and 12(+) isomers in Pb-192,Pb-194, described by the 3s(1/2)(-2)1h(9/2)1i(13/2) intruder two-proton and 1i(13/2)(2) two-quasi neutron configurations, respectively, have been determined by the method of time-differential observation of the gamma-ray perturbed angular distribution. The derived values are vertical bar Q(s)vertical bar(12(+),Pb-192) = 0.32(4) eb, vertical bar Q(s)vertical bar(11(-),Pb-192) = 2.9(3) eb and vertical bar Q(s)vertical bar(11(-),Pb-194) = 3.6(4) eb. The 8(+) 2304 keV and 9(-) 2514 keV states in Pb-192 have been identified as isomers, with half-lives of 3.9(3) and 3.3(2) ns, respectively. The experimental spectroscopic quadrupole moments for the 11(-) and 12(+) isomers in neutron deficient Pb nuclei have been described in the framework of the pairing plus quadrupole model. The intrinsic quadrupole moments and deformation of the 11(-) isomers are compared with the predictions of mean-field and interacting boson models. (C) 2007 Elsevier B.V.

Background: The lead region, Po, Pb, Hg, and Pt, shows up the presence of coexisting structures having different deformation and corresponding to different particle-hole configurations in the Shell Model language. Purpose: We intend to study the importance of configuration mixing in the understanding of the nuclear structure of even-even Po isotopes, where the shape coexistence phenomena are not clear enough. Method: We study in detail a long chain of polonium isotopes, 190-208Po, using the interacting boson model with configuration mixing (IBM-CM). We fix the parameters of the Hamiltonians through a least-squares fit to the known energies and absolute B(E2) transition rates of states up to 3 MeV. Results: We obtained the IBM-CM Hamiltonians and we calculate excitation energies, B(E2)'s, electric quadrupole moments, nuclear radii and isotopic shifts, quadrupole shape invariants, wave functions, and deformations. Conclusions: We obtain a good agreement with the experimental data for all the studied observables and we conclude that shape coexistence phenomenon is hidden in Po isotopes, very much as in the case of the Pt isotopes., To be published in Physical Review C. arXiv admin note: text overlap with arXiv:1312.4595

The nucleus Fr-203 has been studied through gamma-ray and electron spectroscopy, using the recoil-decay tagging technique. A 13/2(+) state, with a half-life of 0.37(5) mu s, has been observed in Fr-203. Both the alpha-decay branch and the internal de-excitation of the 1/2(+) isomer in Fr-203 have been studied. Furthermore, the corresponding 1/2(+) state, with a half-life of 0.31(8) s, has been found in At-199. In addition, transitions feeding the 9/2(-) ground state of Fr-203 have been identified. The observed level pattern suggests that the ground state is still spherical.

The Fire Research Laboratory of the Division of Building Research, National Research Council of Canada (DBR/NRC), has been engaged in applied materials research for the past twenty years. The accumulated information has so far remained largely unpublished. Frequent requests from other research laboratories and from industry have brought out the need to release it to the public. Because the information is visualized to benefit fire safety specialists primarily, the material properties in their spheres of interest will be given prominent attention. Those properties are: specific heat, Cp; density, p; thermal conductivity, k; and thermal diffusivity, k, in the case of materials that are, in general, used to form a major part of the mass of non-load- bearing building components, or which are used as protection for load-bearing components., Depuis 20 ans, le Laboratoire de recherche sur l'incendie de la Division des recherches sur le bâtiment du Conseil national de recherches du Canada (DRB/CNRC) travaille dans le domaine de la recherche appliquée sur les matériaux. Jusqu'à présent, le gros des données que le laboratoire a accumulées demeure inédit, mais les demandes de renseignements qu'on reçoit souvent d'autres laboratoires de recherche et de l'industrie soulignent que la publication s'impose. On présume que cette information intéressera surtout les spécialistes de la sécurité-incendie et, par conséquent, on prêtera une attention particulière aux propriétés des matériaux dans les domaines qui intéressent ces experts. Ces propriétés comprennent notamment : la chaleur massique, Cp; la densité, p; la conductivité thermique, k; et la diffusivité thermique, k, dans le cas de matériaux qui constituent, en général, une partie importante de la masse des composants non porteurs de bâtiments ou qui servent à protéger les composants porteurs.

Collinear laser spectroscopy was performed on the 63,64,66,68−82Ga isotopes with neutron numbers from N = 32 to N = 51. These measurements were carried out at the ISOLDE radioactive ion beam facility at CERN. Here we present the nuclear mean-square charge radii extracted from the isotope shifts and, for the lighter isotopes, new spin and moment values. New ground-state nuclear spin and moments were extracted from the hyperfine spectra of 63,70Ga, measured on an atomic transition in the neutral atom. The ground-state spin of 63Ga is determined to be I = 3/2. Analysis of the trend in the change in mean-square charge radii of the gallium isotopes demonstrates that there is no evidence of anomalous charge radii behavior in gallium in the region of N = 32. ispartof: Physical Review C, Nuclear Physics vol:86 issue:3 status: published

Background: The Po, Pb, Hg, and Pt region is known for the presence of coexisting structures that correspond to different particle-hole configurations in the Shell Model language or equivalently to nuclear shapes with different deformation. Purpose: We intend to study the configuration mixing phenomenon in the Hg isotopes and to understand how different observables are influenced by it. Method: We study in detail a long chain of mercury isotopes, $^{172-200}$Hg, using the interacting boson model with configuration mixing. The parameters of the Hamiltonians are fixed through a least square fit to the known energies and absolute B(E2) transition rates of states up to $3$ MeV. Results: We obtained the IBM-CM Hamiltonians and we calculate excitation energies, B(E2)'s, quadrupole shape invariants, wave functions, isotopic shifts, and mean field energy surfaces. Conclusions: We obtain a fairly good agreement with the experimental data for all the studied observables and we conclude that the Hamiltonian and the states we obtain constitute a good approximation to the Hg isotopes., We are very grateful to K. Wrzosek-Lipska, E. Rapisarda, and L. Gaffney for generous sharing of theirmost recent results on Coulomb excitation (A = 182-188), beta-decay results for A = 182 and A = 184 and new lifetime data for A = 184 and A = 186. We thank M.

The role of intruder configurations in the description of energy spectra and B(E2) values in the Pt region is analyzed. In particular, we study the differences between Interacting Boson Model calculations with or without the inclusion of intruder states in the even Pt nuclei $^{172-194}$Pt. As a result, it shows that for the description of a subset of the existing experimental data, i.e., energy spectra and absolute B(E2) values up to an excitation energy of about 1.5 MeV, both approaches seem to be equally valid. We explain these similarities between both model spaces through an appropriate mapping. We point out the need for a more extensive comparison, encompassing a data set as broad (and complete) as possible to confront with both theoretical approaches in order to test the detailed structure of the nuclear wave functions., Comment: To be published in NPA

- Abstract
In this paper we study the effect of well-known higher-order corrections to the allowed beta-decay spectrum on the determination of antineutrino spectra resulting from the decays of fission fragments. In particular, we try to estimate the associated theory errors and find that induced currents like weak magnetism may ultimately limit our ability to improve the current accuracy and under certain circumstance could even greatly increase the theoretical errors. We also perform a critical evaluation of the errors associated with our method to extract the antineutrino spectrum using synthetic beta spectra. It turns out that a fit using only virtual beta branches with a judicious choice of the effective nuclear charge provides results with a minimal bias. We apply this method to actual data for (235)U, (239)Pu, and (241)Pu and confirm, within errors, recent results, which indicate a net 3% upward shift in energy-averaged antineutrino fluxes. However, we also find significant shape differences which can, in principle, be tested by high-statistics antineutrino data samples.

- Abstract
This ramjet cost handbook is a result of work conducted under Air Force Contract F33615-76-C-2043 to generate cost data and to establish a cost methodology that will accurately predict the production costs of ramjet engines. The cost handbook contains a description of over one hundred and twenty-five different components which are defined as baseline components. The cost estimator selects from the handbook the appropriate components to fit his ramjet assembly, computes the cost from cost computation data sheets in the handbook, and totals all of the appropriate cost elements to arrive at the total engine cost. The methodology described in the cost handbook addresses many different ramjet types from simple podded arrangements of the liquid fuel ramjet to the more complex integral rocket/ramjet configurations including solid fuel ramjets and solid ducted rockets. It is applicable to a range of sizes from 6 in. diameter to 18 in. diameter and to production quantities up to 5000 engines. (Author), See also Rept. no. AFAPL-TR-77-50-VOL-1, AD-A054 856.

- Abstract
A set of individual data sheets for gas phase chemical reactions and photochemistry of neutral species is presented. These data sheets give preferred values for reaction rate constants, photoabsorption cross sections and quantum yields with a brief statement discussing the basis for the preferred value. Recent experimental results are also given. The coverage of this initial set of data sheets issued in February 1980 corresponds to the approximately 400 reactions listed in NBS Special Publication 513, R. F. Hampson and D. Garvin, May 1978. For approximately one quarter of these reactions the data entry has been updated to include the 1979 recommendations of the NASA panel for Data Evaluation and the CODATA Task Group on Chemical Kinetics. They are intended to provide the basic physical chemical data needed as input data for calculations modeling atmospheric chemistry. Revisions and additions for specific reactions will be published as new information becomes available.

- Abstract
Intensive archaeological survey was conducted at 11 Jd 126, a multi-component archaeological site on the lowland flood plain of the Mississippi River, Jo Daviess County, Illinois by Great Lakes Archaeological Research Center, Inc. during September and October, 1982. The objectives of the survey and testing were to delineate the boundaries of the site, refine the site geomorphology and occupational history, and provide additional information required for management of the site as well as for future research at 11 Jd 126. Five archaeological components were identified: (1) a Trempealeau/McGregor Phase component; (2) an Allamakee/Millville Phase component; (3) a Maples Mills component; (4) a Keyes Phase (Effigy Mound) component; and (5) a late 18th century Euro-American component. Sub-surface features at the site, which is buried under recent alluvium include storage pits, sheet midden, and a late 18th century domestic structure. Construction activities at 11 Jd 126 had destroyed a shell midden, and others may occur at the site. Approximately 90% of 11 Jd 126 remains undisturbed. The recovery of carbonized floral remains, faunal remains, and diagnostic cultural materials from buried, stratified contexts, indicates that the site has high potential for research relating to Middle Woodland, Late Woodland, and 18th century occupation of the lowland flood plain in the Quad-state region.
