【 摘 要 】

For many nuclei beyond the proton drip line in the Z greater than 72, N greater than 82 region, both proton and a emission are energetically allowed. In the case of some proton emitters, there are (alpha)-decay chains emanating from both parent and daughter nuclei. This means that if the mass excess of one member of an (alpha)-decay chain is known, then the mass excesses for all members of both chains can be obtained. In addition, proton separation energies may be derived for nuclei in the (alpha)-decay chain of the proton emitter. The method of time- and space-correlations also allows the identification of isomeric states in these nuclei. As an example, a large number of mass excesses and proton separation energies for ground and metastable states have been derived from Q(sub a) and Q(sub p) values obtained from the proton emitters (sup 165,166,167)Ir, (sup 171)Au, (sup 177)Tl, and their daughters.
