  • New measured differential cross sections of tritons and alpha particles following the {sup 6}Li(n,t){alpha} reaction are reported for incident neutron energies between 0.2 and approximately 20 MeV. The neutrons were produced by spallation at the WNR facility at the Los Alamos Neutron Science CEnter (LANSCE), with the incident neutron energy determined by the time-of-flight method. Four E-{Delta}E telescopes were used at eight laboratory angles. These data have been incorporated into a prior R-matrix fit for the compound {sup 7}Li system, and result in an (n,t) reaction cross section that is 4% to 10% higher than previous evaluations in the 1-3more » MeV incident neutron energy region.« less
  • We have completed a new set of total cross section measurements, snd have measured approximately 36 additional samples. The goal of the new measurements was 1% statistical accuracy in 1% energy bins with systematic errors less than 1%. This was achieved for all but the smallest samples, for which the statistical accuracy was as large as 2% in 1% bins. However, the energy resolution is significantly better than this at low energies. The samples were: * The APT spallation target material: W * Medium-mass stmctural materials: Ti, V, Cr, Mn, Fe, Co, Ni * Actinides: Th, depleted U * Othermore » materials for global optical model development: F, Mg, P, S, K, Y, Mo, In, Au, Hg, natural Pb * Separated isotopes of light nuclei: {sup 6}Li%, {sup 7}Li, {sup 10}B, {sup 11}B, {sup 13}C, * Medium- and heavy-mass separated isotopes: {sup 54,56}Fe, {sup 182,183,184,186}W * Few-nucleon physics: H, D.« less
  • An elemental carbon target enriched to 66% in C/sup 13/ was bombarded with 14.8-Mev deuterons. The triton group corresponding to the 7.65-Mev level in C/sup 12/ was magnetically analyzed and detected with scintillator at laboratory angles between 10 and 70 degrees. The angular distribution shows good agreement with Butler theory for 1/sub n/- 1, r/sub o/ = 5.5 x 10/sup -13/ cm; the cross section at the maximum of the angular distribution is 0.38 plus or minus 20% mb/ sterad. The reduced width of the level relative to ground state in C/sup 12/ is 0.043. (auth)
  • In this paper we will present the results from an experiment studying the {sup 196}Pt(n,xn) reactions for n < 14 at moderate to high angular momentum using the combination of the LANSCE/WNR spallation neutron source and the multi-Ge detector spectrometer, GEANIE.
