A number of angular distributions of protons from the reaction ${\mathrm{Li}}^7(d, p){\mathrm{Li}}^8$ have been measured for a range of incident deuteron energies below 2.5 Mev. These agree remarkably well with a simple form of Butler-Born stripping theory, uncorrected for Coulomb and nuclear effects. A description is given for this unusual agreement in terms of the small $Q$ value, -0.188 Mev, for the reaction.

A resonance in the proton yield is found at an incident deuteron energy of 1.4 Mev which has not been observed in measurements of the $\beta$ yield from this reaction. Angular distributions measured on and around the resonance show no influence of this on the unusually good stripping patterns.
