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

The excitation functions of the (p, 2p) reaction cross sections for the elements ²⁵Mg, ³⁰Si, ⁵⁷Fe, ⁶⁸Zn, ¹¹⁸Sn, ¹⁴²Ce and ¹⁸⁶W 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.
