Magnetic Analysis ofBe9(d,α)Li7andBe9(d,p)Be10Reactions

Abstract

The alpha-particle and proton groups arising from the deuteron bombardment of beryllium targets have been studied with a high resolution magnetic spectrometer. Except for the well-known one at 480 kev, no evidence has been found for energy levels in ${\mathrm{Li}}^7$ between 3.4 Mev and the ground state. The $Q$-value for the ${\mathrm{Be}}^9(d,\alpha ){\mathrm{Li}}^7$ reaction has been measured as 7.145±0.024 Mev. Studies of the proton groups indicate that there are no levels in ${\mathrm{Be}}^{10}$ between the ground state and one at 3.375±0.010 Mev. The $Q$ for the ${\mathrm{Be}}^9\mathrm{}(d,p)\mathrm{}{\mathrm{Be}}^{10}$ reaction has been found to be 4.576±0.012 Mev.
