μ−partial capture rates inB10,C12, andN14

Using the short pulses of a linac, a measurement has been performed of partial ${\mu }^{-}$-capture rates in ${}_{}{}^{10}{}_{}{}^{}\mathrm{B}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$, and ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ leading, respectively, to the bound excited states of ${}_{}{}^{10}{}_{}{}^{}\mathrm{Be}$, ${}_{}{}^{12}{}_{}{}^{}\mathrm{B}$, and ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}$. These rates are deduced from the intensities of the observed de-excitation nuclear $\gamma$ rays. A theoretical discussion is given based upon 1$p$-shell models and mesonic exchange currents.
