摘要

A statistical theory of light nucleus reactions (STLN) is proposed to describe both neutron and light charged particle induced nuclear reactions with 1p-shell light nuclei involved. The dynamics of STLN is described by the unified Hauser-Feshbach and exciton model, in which the angular momentum and parity conservations are strictly considered in equilibrium and pre-equilibrium processes. The Coulomb barriers of the incoming and outgoing charged particles, which significantly influence the open channels of the reaction, can be reasonably considered in the incident channel and different outgoing channels. In kinematics, the recoiling effects in various emission processes are strictly taken into account. The analytical double-differential cross sections of the reaction products in sequential and simultaneous emission processes are obtained in terms of the new integral formula proposed in our recent paper [Phys. Rev. C 92, 061601(R) (2015)]. Taking the Be-9(p, xn) reaction as an example, we calculate the double-differential cross sections of outgoing neutrons and charged particles using the PUNF code in the frame of STLN. The existing experimental double-differential cross sections of neutrons at E-p = 18 MeV can be remarkably well reproduced, which indicates that the PUNF code is a powerful tool to set up "file-6" in the reaction data library for light charged particle induced nuclear reactions with 1p-shell light nuclei involved.
