The angular distributions of the cross sections for the $\mathrm{T}(d, n){\mathrm{He}}^4$ and ${\mathrm{He}}^3(d, p){\mathrm{He}}^4$ reactions have been measured at five incident deuteron energies between 6 and 14 Mev. The data have been fitted with Legendre expansions. A search for excited states in ${\mathrm{He}}^4$ near 22 Mev and for evidence of the formation of ${\mathrm{H}}^4$ gave negative results.
