(p, a) and (p, ab) Reactions at 100 Mev

Nuclear reactions at energies of the order of 100 Mev and higher are considered as being divided into two independent steps, a knock-on process followed by nucleon evaporation. The effect of the knock-on process is evaluated by a method similar to that of Goldberger, while the evaporation process is treated in the usual way. Cross sections for several ($p, n$), ($p, 2n$), ($p, \mathrm{pn}$), and ($p, 2p$) reactions on intermediate nuclei are calculated and compared with experimental results.
