Description
Summary:— The binding energy of unknown nuclei far from the line of stability is calculated using local mass relations that describe proton–neutron correlations. The calculations are quite accurate, and a correction of the approximation is proposed that allows the accuracy of the estimates to be improved further. The positions of the boundaries of the existence of atomic nuclei are predicted on the basis of new estimates of the binding energies. Results from modeling the nucleosynthesis products yield in the neutron excess region depend strongly on the choice of the mass model.
