Neutron Emission Spectra of Triton Beams of 20.22-MeV Fully Stopped in Targets of H_2O, D_2O, LiF, Si, Ni, Mo, Ta, W, Pt, and Au

摘要

The Ion Beam Facility of Los Alamos National Laboratory could routinely provide accelerated bunched triton beams to be used in neutron time-of-flight experiments. Exploratory measurements at 0 deg were done to determine the neutron yield with target materials throughout the periodic system yielding absolute specific double-differential neutron yields. Only a few of these measurements were made public previously. The results of these measurements having a mainly demonstrative purpose are presented here because of their uniqueness. For lithium and beryllium, double-differential neutron emission cross sections are given at 17.2 and 15.2 MeV, respectively.
