For clarifying the nature of the γ-ray background observed in H profiling measurements of a LiAl-silicate glass with the 15N nuclear reaction technique, a γ-ray spectroscopy study was carried out using a Ge(Li) detector and 6,7LiF targets. The energies of a great number of γ-ray transitions arising from 6,7Li + 15N reactions were determined and the γ-ray emitting product nuclei 20,21Ne, 18,19,20,21F, 16,17,18O and 13C were identified. The excitation functions of γ-transitions, measured in the 15N energy range 6.0 MeV to 13.4 MeV, were found to vary smoothly with energy and to rise by about three orders of magnitude in this range. Based on these data, a procedure for background correction in spectra taken with a NaI(Tl) scintillation detector could be set up and was used for H profiling of glass samples containing up to 7 at.% lithium.
