Study of Some Reactions of 14.8-Mev Deuterons with the Lithium Isotopes

Abstract

Metallic targets of enriched ${\mathrm{Li}}^5$ and ${\mathrm{Li}}^7$ were bombarded with 14.8-Mev deuterons. The outgoing particles were magnetically analyzed and detected in nuclear emulsions or scintillation counters. Angular distributions for the following reactions were measured: ${\mathrm{Li}}^6(d, p){\mathrm{Li}}^{7*}$ 4.6 and 7.46 Mev. ${\mathrm{Li}}^7(d, p){\mathrm{Li}}^{8*}$ 2.28 Mev, ${\mathrm{Li}}^7(d, t){\mathrm{Li}}^{6*}$ 3.57 Mev, ${\mathrm{Li}}^6(d, d^{\prime }){\mathrm{Li}}^{6*}$ 2.19 Mev, ${\mathrm{Li}}^6(d, \alpha ){\mathrm{He}}^4$ ground state, ${\mathrm{Li}}^6(d, t){\mathrm{Li}}^5$ and ${\mathrm{Li}}^6(d, {\mathrm{He}}^3){\mathrm{He}}^5$. A search was made for other levels produced in these reactions and in the ${\mathrm{Li}}^7(d, d^{\prime }){\mathrm{Li}}^{7*}$ reaction. No new levels were observed; upper limits on the cross sections of unobserved levels are given. The results of the ($d, p$), ($d, t$), and ($d$, ${\mathrm{He}}^3$) reactions were compared with stripping theory and with the predictions of the shell model. The agreement is, in general, satisfactory.
