Abstract

This paper is a sequel to an article describing a simple procedure for the evaluation of heavy-mass (n, 2n) and (n, 3n) cross-sections. The neglect of pre-compound effects in the energy range above the (n, 3n) threshold leads to an overestimation of σn, 3n(E), at the expense of σn, 2n(E). Pre-compound effects on σn, 2n(E) and σn, 3n(E) can be estimated through the use of simple evaluation formulae, derived from basic, more involved integrals. Agreement between evaluation and experiment is much improved in the energy range above the (n, 3n) threshold.
