  ABSTRACT: Double-differential cross sections for light charged particle production (up to A=4) were measured in 96 MeV neutron-induced reactions, at TSL laboratory cyclotron in Uppsala (Sweden). Measurements for three targets, Fe, Pb, and U, were performed using two independent devices, SCANDAL and MEDLEY. The data were recorded with low energy thresholds and for a wide angular range (20-160 degrees). The normalization procedure used to extract the cross sections is based on the np elastic scattering reaction that we measured and for which we present experimental results. A good control of the systematic uncertainties affecting the results is achieved. Calculations using the exciton model are reported. Two different theoretical approches proposed to improve its predictive power regarding the complex particle emission are tested. The capabilities of each approach is illustrated by comparison with the 96 MeV data that we measured, and with other experimental results available in the literature. Comment: 21 pages, 28 figures

  ABSTRACT: Experimental light-particle production double-differential cross sections are reported for 62.9 MeV proton-induced reactions on 208 Pb. Light charged particle (p, d, t, 3 He and 4 He) double-differential cross sections were measured from 25° to 155° by step of 10 degrees with a set of Si-Si-CsI telescopes. Neutron double-differential cross sections were measured at 24°, 35°, 55°, 80° and 120° with DeMoN counters. Energy-differential, angular-differential and total production cross sections are also presented. These data are compared to theoretical calculations (MCNPX, FLUKA and TALYS).
