The absolute cross section for the ${\mathrm{Li}}^7(d, p){\mathrm{Li}}^8$ reaction has been measured from 700 kev to 3.3 Mev. Previously reported resonances are located at 800 kev and 1.04 Mev, corresponding to states in ${\mathrm{Be}}^9$ at 17.30 Mev and 17.49 Mev, respectively. A third resonance, indicated by the earlier work to be at 1.4 Mev, is not confirmed, from which it is concluded that ${\mathrm{Be}}^9$ does not have the 17.8-Mev level for which that reported resonance was evidence. Above 1.8 Mev, the yield is relatively flat, perhaps indicating the influence of stripping, rather than compound nucleus formation.
