Excited States ofB11andB12from the ReactionsB10(d, p)B11andB11(d, p)B12

Abstract

Evaporated targets of natural boron and enriched ${\mathrm{B}}^{10}$ deposited on thin Formvar films were bombarded with deuterons produced by the MIT-ONR Van de Graaff accelerator. Incident energies from 4.0 to 8.5 Mev were used, and charged particles leaving the target at 90 degrees to the deuteron beam direction were analyzed by a 180-degree magnetic spectrograph. The studies covered a region of excitation from 7.50 to 11.46 Mev in ${\mathrm{B}}^{11}$, and from zero to 3.40 Mev in ${\mathrm{B}}^{12}$.
