ResumoWe have made the first determination of relative cross sections for the population of individual ${\mathit{M}}_{\mathit{L}}$ substates in a double-electron capture collision by measuring the angular distribution of electrons emitted in the Auger decay of doubly excited 1s2l2l${\mathcal{'}}^{2}$L states of ${\mathrm{C}}^{3+}$ formed in ${\mathrm{C}}^{5+}$+He collisions. Large anisotropies were observed for the 1s2${\mathit{p}}^{2}$ $^{2}$D and 1s(2s2p $^{1}$P${)}^{2}$${\mathit{P}}^{\mathit{o}}$ terms which varied markedly with projectile velocity in the range 0.29--0.50 a.u. A strong velocity variation was also observed for the total L-subshell relative cross sections.
