Angular Distributions of Deuteron-Induced Reactions in Lithium

Abstract

Angular distributions of ($d, t$), ($d$, ${\mathrm{He}}^{3}$), ($d, p$), and ($d, {d}^{\ensuremath{'}}$) reactions have been obtained using a natural lithium target. Butler type calculations for $l=1$ transfer fit all of the above data except for the ($d, {d}^{\ensuremath{'}}$) reactions. A $Q$-value of 0.974\ifmmode\pm\else\textpm\fi{}0.015 Mev has been assigned to the first excited level in ${\mathrm{Li}}^{8}$. The ${\mathrm{He}}^{5}$ ground state was observed with the two reactions ${\mathrm{Li}}^{7}(d, \ensuremath{\alpha}){\mathrm{He}}^{5}$ and ${\mathrm{Li}}^{6}(d, {\mathrm{He}}^{3}){\mathrm{He}}^{5}$ for which the $Q$ values were 14.26\ifmmode\pm\else\textpm\fi{}0.09 Mev and 0.91\ifmmode\pm\else\textpm\fi{}0.09 Mev, respectively.
