14.4-Mev (n, 2n) Cross Sections

Abstract

Cross sections for the ($n, 2n$) reaction have been measured at an incident neutron energy of 14.4±0.3 Mev for 27 nuclides. These measurements were made relative to the cross section for the ${\mathrm{Cu}}^{63}(n, 2n){\mathrm{Cu}}^{62}$ reaction. The relative cross sections were then converted to absolute cross sections by using the weighted mean of several ${\mathrm{Cu}}^{63}(n, 2n){\mathrm{Cu}}^{62}$ reaction-cross-section measurements made by other investigators.
