Differential cross sections are obtained for the reactions $v_{\mu }+{}_{}{}^{12}{}_{}{}^{}\mathrm{C}\to {}_{}{}^{12}{}_{}{}^{}\mathrm{N}+{\mu }^{-}$ and $e^{-}+{}_{}{}^{12}{}_{}{}^{}\mathrm{C}\to {}_{}{}^{12}{}_{}{}^{}\mathrm{B}+v_e$ for incoming lepton energies of 1 and 3 GeV. The contributions of individual form factors to the differential cross section are also found. A discussion of the utility of these processes for studying the weak nuclear current is given.
