Abstract
The masses of the light elements as far as fluorine have been calculated by Dr. M. L. Oliphant from the data given by Aston in NATURE of February 29, together with transformation data. The large mass found for the neutron (1-0091) is difficult to reconcile with the hypothesis that the proton and neutron are interconvertible elementary particles. By plotting the departure of the atomic masses from a whole number against the mass-number, Oliphant makes interesting deductions concerning the stability of several atomic species and predicts the probable existence of helium of mass 5-0125, the only mass-number missing from the list.
