Mass determination of the nuclei 12N, 16F, 22Mg and 26Si using the (3He, n) reaction

Fast neutron time-of-flight studies of (3He, n) reactions have been used to obtain information on four proton-rich nuclei. The ground-state reaction Q values, and hence atomic masses, and mass excesses have been determined together with the energies of several of the low-lying levels of these nuclei. The results are consistent with other recent determinations, but the values presented here are more precise. In all cases there is disagreement with the 1964 Mass Tables.
