摘要：

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 0d3/2-0f(f/2) shell-model mass extrapolations, 39Ti, 42Cr, 45Fe, 48Ni, and 49Ni 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 39Ti, 45Fe, and 48Ni are found to be promising for further experimental investigation.
