Atomic Masses of the Stable Isotopes,10≤A≤30

Abstract

The masses of all stable isotopes in the range $10\le A\le 30$ have been measured using the large double-focusing mass spectrometer recently constructed at this laboratory. No serious discrepancies are found between the present results and other mass spectroscopic measurements except at ${\mathrm{Ne}}^{20}$. The masses calculated from nuclear reaction energies are, with the exception of ${\mathrm{F}}^{19}$, lower than the present results.
