Abstract
The process of direct two-proton decay of nuclei with Z=22–28 on the proton drip line is considered. On the basis of new 0-0 shell-model mass extrapolations, , , , , and are found to be bound to single-proton decay but unbound to two-proton decay. New estimates of the spectroscopic factors and lifetimes have been made. The decays of , , and are found to be promising for further experimental investigation.
