“…While the angular distributions are not inconsistent with isotropy, it is reasonable to suggest the existence of peaks at 50 and 120°. This suggestion may also be made concerning the angular distributions of protons ejected from nickel by 21 MeV bremsstrahlung (Lejkin, Osokina, and Ratner 1956). Similar peaks were obtained by Toms and Stephens (1955) for tantalum photoprotons.…”

It has been shown that the energy and angular distribution of photoprotons from middle-weight nuclei (Z about 30) can be almost entirely accounted for by the statistical theory of nuclear reactions (Byerly and Stephens 1951; Toms and Stephens 1954). The evidence indicates that the direct photo effect contributes only a small amount to the emitted photoproton spectrum. However, the statistical theory does not explain, among other things, why the photoproton yield at 23 MeV from copper and nickel should be about three times that from cobalt (Mann and Halpern 1951).

“…On the basis of the present study and that of Lejkin, Osokina, and Ratner (1956), it is concluded that, though statistical theory can account for the energy distribution of all or most of the photoprotons emitted from. nickel, the angular ·distribution shows evidence of peaks.…”
