Exploring the limits of existence of proton-rich nuclei in the region
Résumé
-, -, and proton-decay energies have been combined with TITAN mass values for to expand and refine the mass surface in the proton-rich region. The calculations were performed using the Atomic Mass Evaluation (AME) algorithm, resulting in 11 new ground-state masses and uncertainty reductions of nine others. The new information allows the determination of the two-proton drip line for elements between Ir and Pb and provides indications of possible new candidates for two-proton emission. In addition, we examined binding energies in this region for Thomas-Ehrman shifts, so far only visible for light nuclides.
