We have measured the absolute spectra for the yield of high-energy tritons for the process ${}_{}{}^3{}_{}{}^{}\mathrm{He}(d, t)2p$ at 24 MeV c.m. Elastic scattering of deuterons from ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ has also been measured at the same c.m. energy. The reaction data are characterized by forward and backward peaking and by a deep minimum near 90° c.m. The forward-angle triton spectrum is consistent with a simple pickup process. A comparison of the forward-angle triton yield to the cross section for elastic scattering at back angles provides strong evidence both for the dominance of the pickup process at small angles in the reaction and for the importance of this process to back-angle elastic scattering.

NUCLEAR REACTIONS ${}_{}{}^3{}_{}{}^{}\mathrm{He}(d, t)$ and ${}_{}{}^3{}_{}{}^{}\mathrm{He}(d, d)$, $E=23.5\mathrm{}$ MeV c.m., measured $d\sigma (E_t, 10°-180\mathrm{}° \mathrm{c}.\mathrm{m}.\mathrm{})$.
