Abstract
Double-differential cross section (DDX) data of nucleon-actinide reactions is crucial for the study of nuclear waste transmutation by accelerator driven systems. Charged particle emission data is strongly required as well as the neutron data up to several Gev. In the present study, we measured double-differential cross sections of light charged particle productions for proton induced reactions on 232Th at 360Mev. The experiment was carried out at the PHASOTRON facility of the Joint Institute for Nuclear Research (JINR) in Dubna.

The light charged particles (LCPs) emitted from nuclear reactions were detected by ∆E-E counter telescopes. Eight detector systems were used. Four of them were comprised of two plastic scintillator plates and BGO crystal. The other four consisted of two silicon semiconductor detectors and two scintillation counters, a cubic CsI(TI) (40 mm long) crystal and plate plastic scintillator. The four identical detectors on each side were placed at laboratory angles of 20o. 40o, 70o and 105o with respect to the beam axis. Resultant DDX spectra of protons and deuterons were compared with intranuclear cascade (INC) model.
