The differential cross section for the reaction ${\mathrm{Li}}^7(d, {\alpha }_0){\mathrm{He}}^5$ (ground state) was measured to be 0.31±0.10, 0.64±0.22, 1.04±0.36, 1.41±0.49, and 1.71±0.60 mb/sr for incident deuteron energies of 175, 214, 248, 280, and 300 keV, respectively, relative to that for the reaction ${\mathrm{Li}}^6(d, \alpha ){\mathrm{He}}^4$. The energy dependence of the measured cross sections agreed with that for the probability of formation of the compound nucleus, calculated from continuum theory.
