Survey of (p, n) Reactions at 12 Mev

Abstract

Results of measurements of twenty ($p, n$) cross sections on elements from atomic number 21 to 58 are given. The data indicate total reaction cross sections which, when interpreted in terms of a totally black square well potential of depth 20 Mev, correspond to a potential radius of 1.55 to $1.65A^{\frac{1}{3}}\times {10}^{-13\mathrm{}}$ cm.
