Secondary Light Charged Particle Emission from the Interaction of 25-65 MeV Neutrons on Uranium

摘要

Double-differential cross sections for light charged particle production in fast-neutron induced (n,px), (n,dx), (n,tx) and (n,αx) reactions on uranium were measured in the incident neutron energy range 25-65 MeV and at laboratory angles from 20° to 160°. In this paper, only a quick review of the experimental arrangement and data reduction procedures will be given. Preliminary inclusive emission spectra for hydrogen isotopes will be shown. From the double-differential cross sections, angle- and energy-differential cross sections as well as total production cross sections are deduced. The measurements are compared to nuclear model calculations which include preequilibrium and equilibrium decay mechanisms: the Liege intranuclear cascade model (INCL) and the GNASH nuclear data code.
