valuation of the Maxwellian averaged cross section (MACS) at kT = 30 keV

Abstract

This study presents the derivation of a formula for the calculation of Maxwellian Averaged neutron capture Cross Sections (MACS) at 30 keV. Utilizing this derived formula, we establish a linear correlation between the logarithm of MACS at 30 keV divided by A1.4 and (N-Z)2/A2 of the target nucleus. The calculated MACS values, obtained from this correlation, exhibit satisfactory agreement with experimental data, indicating the useful of this new systematic law for analyzing experimental data. Furthermore, this systematic law facilitates the estimation of MACS for neighboring isotopes where experimental data are limited or unavailable.
