Direct and compound contributions to (n, ?) cross sections

Abstract

We have investigated the direct and compound nucleus contributions to the 2~ (n, 7) z~ reaction in the region 2.25-7.25 MeV. We have used for the compound nucleus cross sections a modified Hauser-Feshbach theory in the presence of direct reactions. The corrections to the traditional Hauser-Feshbach theory are found to be small in this case.
