Experimental cross sections for light-charged particle production induced by neutrons with energies between 25 and 65 MeV incident on oxygen

摘要

Experimental double-differential cross sections (d~2#sigma#/d#OMEGA#dE) for last neutron-induced proton, deuteron, triton, and alpha-particle production on oxygen are reported at several incident neutron energies between 25 and 65 MeV for outgoing particle energies above the experimental energy detection thresholds. Angular distributions were measured at laboratory angles between 20 deg and 160 deg. Reliable extrapolated spectra are obtained at very forward (2.5 deg and 10 deg) and at very backward (170 deg and 177.5 deg) angles. Based on these experimental data, energy-differential (d#sigma#/dE), angle-differential (d#sigma#d#OMEGA#), and total cross sections (#sigma#_#tau#) are reported for each detected particle.
