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 − ,νn) 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.
