Analysis of 14-Mevn−pScattering

Abstract

The total $n-p$ cross section at 14.10±0.05 Mev is calculated for several choices of the $n-p$ singlet potential well parameters for each of the potential well shapes: square, exponential, and Yukawa. These calculations are compared with the experimental result for the cross section at this energy, ${\sigma }_{\mathrm{total}}=0.689\mathrm{}\pm 0.005$ barn. Limits on the values of the effective range, the intrinsic range, and the depth of the singlet potential are obtained for each well shape
