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

Abstract

Many new $γ$-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($μ^{-}$,$ν$n)$^{13}$C compare favourably with states observed in the reaction $^{14}$N($γ$,p)$^{13}$C. More precise energies are also given for the 7017 and 6730 keV $γ$-rays in $^{14}$C.
