The differential muon-capture rate $\frac{\mathrm{d}\Gamma }{\mathrm{d}\Omega }({}_{}{}^6{}_{}{}^{}\mathrm{Li}+{\mu }^{-}\to {}_{}{}^3{}_{}{}^{}\mathrm{H}+{}_{}{}^3{}_{}{}^{}\mathrm{H}+{\nu }_{\mu })$ as a function of angle between the outgoing tritons is calculated by the use of the elementary particle model. The total capture rate for the same reaction but with the neutrino energy limited between 0 and 29.8 MeV is also calculated as is the rate $\frac{d\Gamma }{d\nu }$ under the same limitation. The reaction is also discussed as a candidate for determining a better limit on the muon-neutrino mass.
