Abstract
The gamma rays resulting from the bombardment of B 10 with protons of energies from 0.5 to 2.0 Mev. have been observed with a sodium iodide scintillation counter. Capture radiation, of energy[Formula: see text]showed a broad resonance at E p = 1135 ± 15 kev. At this energy, the radiation had an angular distribution of the form 1 + (0.50 ± 0.05)cos 2 θ and a total cross section (3.5 ± 1.0)10 −30 cm. 2 Several lower energy radiations were also observed and assigned tentatively to cascade transitions in C 11 .The cross section for the 430 kev. radiation from the reaction B 10 (p, αγ)Be 7 was found to be 0.21 ± 0.05 barn at E p = 1.52 Mev. This radiation was found to be isotropic.
