Abstract

Beams of 185–204 MeV

{}^{40}{Ca}

ions have been used to bombard

{}^{92}{Mo}

{}^{96}{Ru}

{}^{102}{Pd}

, and

{}^{106}{Cd}

targets in order to produce the proton-decay candidate nuclei

{}^{128}{Pm}

{}^{132}{Eu}

{}^{138}{Tb}

, and

{}^{142}{Ho}

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 β decay.
