Abstract

New exciton model of preequilibrium decay (MCP), allowing to compute the spectra of multiparticle emission during an establishment of statistical equilibrium is proposed. Systematic comparison of results of calculations with the experimental spectra of nucleons from (p, xn), (p, xp), (n, xn) and (n, xp) reactions in a wide projectile energy region from 10 up to 60 MeV for targets from 27Al up to 209Bi is carried out.

Keywords
exciton model of preequilibrium decay, MCP, Monte Carlo method, emission spectra sequentially emitted particles, energy distributions of the residual nuclei
