Differential cross sections for the reaction ${\mathrm{e}}^{\mathrm{-}}$${+}^{12}$C→${\nu }_{\mathrm{e}{+}^{12}}$B are obtained for the outgoing nucleus for incoming electron energies of 0.5, 1.5, 3.0, and 6.0 GeV near the maximal angle. A kinematic singularity at the maximal angle is investigated and eliminated by the use of a wave packet.
