Measurement of the decay energies (Qβ) of isotopes which are far removed from the valley of beta stability permits checks of mass theories and provides input for the refinement of mass systematics. In particular, the nuclei which lie on or near the N = Z line with A > 60 are expected to provide some of the most stringent tests of these theories. The nuclei in this region are expected to highlight the influences of a variety of nuclear structure features which affect the nature of the mass surface. These include ison effects, the influences of nuclear shells on binding energies, single particle versus collective phenomena, coulomb energy considerations, symmetry effects, and the role of nuclear deformation in regions of unusual N/Z ratio. In addition to the delineation of the mass surface in these regions, spectroscopic studies of nuclei which lie off of the beta stability line permit additional tests of the detailed predictions of nuclear structure theories.
