μ−partial capture rates inB10,C12, andN14

Abstract

Using the short pulses of a linac, a measurement has been performed of partial ${\ensuremath{\mu}}^{\ensuremath{-}}$-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 $\ensuremath{\gamma}$ rays. A theoretical discussion is given based upon 1$p$-shell models and mesonic exchange currents.[NUCLEAR REACTIONS Muon capture $^{10}\mathrm{B}(\ensuremath{\mu},\ensuremath{\nu})^{10}\mathrm{Be}$, $^{12}\mathrm{C}(\ensuremath{\mu},\ensuremath{\nu})^{12}\mathrm{B}$, and $^{14}\mathrm{N}(\ensuremath{\mu},\ensuremath{\nu})^{14}\mathrm{C}$.
