Energy Levels ofB11from theB10(d,p)B11*Reaction

Abstract

The proton groups from enriched ${\mathrm{B}}^{10}$ bombarded by 1.51-Mev deuterons have been investigated by means of a magnetic spectrograph of high resolution. Eleven proton groups were assigned to the reaction ${\mathrm{B}}^{10}\mathrm{}(d,p)\mathrm{}{\mathrm{B}}^{11}$, corresponding to the ground state and ten excited states of ${\mathrm{B}}^{11}$. Five of these excited states have not been previously reported. At 6.8-Mev excitation of ${\mathrm{B}}^{11}$, a doublet was observed with a level spacing of 50.0±2.0 kev. The range of excitation of ${\mathrm{B}}^{11}$ covered in these experiments was from 0 to 10.2 Mev.
