Using Proton Radioactivity to Locate the Proton Dripline
Abstract
Experiments in proton radioactivity yield the proton decay energy E_p, which in turn gives the proton separation energy S_p. By definition, Sp is negative for nuclides beyond the proton drip line. Except for Z=59 and Z=61, proton emitters have been observed for every odd-Z element in the region Z=51-83. In addition, information from alpha-decay branches of proton emitters allows the derivation of Sp values for the alpha-decay daughter nuclei, providing further information on the mass surface near the proton drip line. The location of the proton dripline for this region will be shown, and compared with the results of various mass predictions.
