Monte Carlo simulations for particle and -ray emissions from a compound nucleus based on the Hauser-Feshbach statistical theory with pre-equilibrium emission are performed. The simulation yields reliable nuclear-reaction-wise energy spectra, or so-called exclusive spectra, for emitted neutrons and -rays, which are required in particle transport calculations for nuclear applications. The Monte Carlo method is applied to neutron-induced nuclear reactions on 56 Fe, and the results are compared with a traditional deterministic method. The neutron and -ray emission correlation is examined by gating on an 847 keV -ray that is produced by an inelastic scattering process. The partial -ray energy spectra for different -ray multiplicities are inferred using this Monte Carlo method. In addition, we investigate a correlation between two neutrons in the (n,2n) reaction.

“…It has been shown that the reaction mechanism can be understood fairly accurately in terms of a series of multiple intranuclear nucleon-nucleon collisions, which finally end in a direct transfer of the emitted particle [1,2]. The reaction mechanism of the direct transfer depends on the incident energy of the projectile and on the ejectile.…”

Abstract. The pre-equilibrium proton induced emission of light complex nuclei with energies in the continuum has been studied comprehensively for many years. Double-differential cross sections and especially analyzing power distributions are typical of an intranuclear nucleon-nucleon multistep statistical reaction mechanism. The final stage of the reaction may be a result of a direct pickup or knockout of the ejectile. The discussion on this subject continues to be a hot topic for both theoretical and experimental investigations. In this paper the results from the latest studies of the inclusive ( p,α) reactions on 59 Co to the continuum will be reported. The formalism based on the statistical multistep direct emission formulation of Feshbach, Kerman and Koonin is found to give a reasonably good reproduction of cross section and analyzing power distributions at various emission energies. Special attention will be paid to the details of the calculations.
