Excitation function for high-energy (p, 2p) reactions

Abstract The excitation functions of the (p, 2p) reaction cross sections for the elements 25 Mg, 30 Si, 57 Fe, 68 Zn, 118 Sn, 142 Ce and 186 W have been calculated in the energy region above 100 MeV. The calculated values are compared with the available experimental results and the agreement between the two is found to be fairly good. The dependence of σ(p,2p) on the target mass number has been explained in terms of the expression derived.
