Abstract
The gamma rays resulting from the bombardment of B10 with protons of energies from 0.5 to 2.0 Mev. have been observed with a sodium iodide scintillation counter. Capture radiation, of energy showed a broad resonance at Ep = 1135 ± 15 kev. At this energy, the radiation had an angular distribution of the form 1 + (0.50 ± 0.05)cos2θ 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 C11.The cross section for the 430 kev. radiation from the reaction B10(p, αγ)Be7 was found to be 0.21 ± 0.05 barn at Ep = 1.52 Mev. This radiation was found to be isotropic.Keywords
