Abstract

The mass differences of 17 doublets involving the atoms H3, He3, He4, C13, C14, N14, N15, O16, and F19 have been measured with a rf mass spectrometer. By least squares adjustment, best values are obtained for the masses of these eight atoms for which the estimated errors are materially less than for previously published values. By using Einstein's mass energy relation, very accurate values are derived for the β decay energies of H3 and C14 and for the neutron binding energies in C13, C14, and N15. The last ones offer a possibility to improve the calibration for multi-MeV (capture) γ rays by an order of magnitude.

NUCLEAR STRUCTURE H3, He3, C13, C14, N14, N15, O16, F19 measured atomic mass. H3, C14 deduced Q. H2(n, γ), He3(n, γ), C12(n, γ), C13(n, γ), N14(n, γ) deduced Q.
