Angular Distributions of theBe9(d, n)B10Neutrons

Abstract

The angular distributions of neutrons to the ground state and to the first excited state of ${\mathrm{B}}^{10}$ in the reaction ${\mathrm{Be}}^9(d, n){\mathrm{B}}^{10}$ have been studied at incident deuteron energies of 1.41 Mev, 1.88 Mev, and 2.35 Mev. A proton recoil spectrometer utilizing a xenon gas scintillation trigger was developed to study this problem. This spectrometer operated with a resolution of the order of 7% at the neutron energies involved in this reaction.
