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.
