The cross section for the capture ${\mathrm{reaction}}^2$H(α,γ${)}^6$Li was measured in the energy range of about ${\mathit{E}}_{\mathrm{\alpha },\mathrm{l}\mathrm{a}\mathrm{b}}$≊2 MeV corresponding to the $3^{+}$ resonance in ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ at ${\mathit{E}}_{\mathit{x}}$=2186 keV. Calculations in a direct-capture model using double-folded α-d potentials reproduce strength and width of this resonance as well as the nonresonant capture cross section at lower and higher energies.
