AN EMPIRICAL APPROACH TO THERMAL NEUTRON ABSORPTION CROSS SECTIONS.

Abstract

A simple procedure is proposed to simulate the cyclic variation of the thermal neutron absorption cross sections of the odd-Z, even-N nuclei. The assumption is made that the cross sections vary with (a) the number of protons in the last open proton shell, and (b) the number of neutron holes in the last open neutron shell. With the major nuclear shells as a basis and with variations as to which subshells are included, empirical results are obtained and compared with the experimental cross-section curve. Preliminary indications are that the proposed method gives results that follow the trend of the experimental data. (Author)
