Abstract

The experimental procedure used in studying the angular distribution of γ-radiation produced by the proton bombardment of some light nuclei is described. Results are given for the radiation following proton capture by the nuclei Li 7 , Be 9 , C 12 , C 13 and for the radiation from the residual O 16* nucleus produced in the reaction F 19 ( p , α) O 16* . Proton energies between 300 and 1000 keV were available. The distribution of the radiation from Li 7 was investigated over the whole range of energies; in the other cases the distribution was measured at energies corresponding to resonance maxima for the processes. The main results are: reaction Li 7 ( p , γ) Be 8 Be 9 ( p , γ) B 10 C 12 ( p , γ) N 13 C 13 ( p , γ) N 14 F 19 ( p , α) O 16* proton energy (keV) 440 960 450 550 330, 470 and 670 590 870 angular distribution 1+ 0.05 cosθ 1 + 0.09 sin 2 θ isotropic isotropic isotropic 1 + 0.2 cos 2 θ 1 + 0.1 cos 2 θ
