Abstract

Utilizing the compound nuclear reaction

{}^{58}{Ni}

+^{50}

Cr and a new low-energy proton detector ball, we have observed the ground-state proton decay of

{}^{105}{Sb}

. A proton energy of 478±15 keV was measured along with an estimated ground-state proton branching ratio of ∼1%, compatible with emission from a

d_{5 / 2}

level and a spectroscopic factor of order unity.
