Angular distributions of ($d, t$), ($d$, ${\mathrm{He}}^3$), ($d, p$), and ($d, d^{\prime }$) reactions have been obtained using a natural lithium target. Butler type calculations for $l=1\mathrm{}$ transfer fit all of the above data except for the ($d, d^{\prime }$) reactions. A $Q$-value of 0.974±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 ${\mathrm{Li}}^7(d, \alpha ){\mathrm{He}}^5$ and ${\mathrm{Li}}^6(d, {\mathrm{He}}^3){\mathrm{He}}^5$ for which the $Q$ values were 14.26±0.09 Mev and 0.91±0.09 Mev, respectively.
