Beams of 185 204 MeV Ca40 ions have been used to bombard Mo92, Ru96, Pd102, and Cd106 targets in order to produce the proton-decay candidate nuclei Pm128, Eu132, Tb138, and Ho142 via the 1p3n fusion evaporation channel. In each case no evidence for proton radioactivity was found. On the basis of mass model systematics it was concluded that the odd proton is not sufficiently unbound in these nuclei for proton emission to compete successfully with decay.
