Photodisintegration of light and medium-weight nuclei at intermediate energies—V

Abstract

The mass-yield dependence of (γ,n) and (γ,p) reactions in the photon energy range (0.2–1) GeV has been investigated. A Monte Carlo calculation for these reactions has been carried out to compare values of the measured cross sections with those arising from different models of interaction. Very good agreement was found between experiment and estimates based on a fast-step, direct character for the reaction mechanism. As a result of the analysis, N- and Z-dependences of mean cross sections are given for the (γ,n) and (γ,p) reactions. Agreement with a more sophisticated theory is also quite reasonable.
