Systematics for the cross-sections of the (n,p) reaction at 14.5 MeV neutron energy

A new empirical formulae for the calculation of the (n, p) reaction cross-sections at 14.5 MeV neutron energy has been proposed. The measured data for (n, p) reaction cross-sections have been collected from the literature and analyzed for the isotopes having 3 ≤ Z ≤ 83. It has been found that σn,p versus Z/A is more effective than σn,p versus Sp. The odd-even effects have been observed as the cross-sections of odd-mass nuclei are higher than those of their neighbouring even-even nuclei. (author)
