Gamma-rays from Muon Capture in ${}^{14}$N

Abstract

Many new $\gamma$-rays have been observed, following muon capture on ${}^{14}$N. One had been reported before, and the low yield is confirmed, indicating that the nuclear structure of ${}^{14}$N is still not understood. Gamma-rays from ${}^{13}$C resulting from the reaction ${}^{14}$N(${\mu }^{-}$,$\nu$n)${}^{13}$C compare favourably with states observed in the reaction ${}^{14}$N($\gamma$,p)${}^{13}$C. More precise energies are also given for the 7017 and 6730 keV $\gamma$-rays in ${}^{14}$C.
