Abstract
Proton radioactivity from the closed neutron shell nucleus Ta-155 has been observed. It was produced via the p4n fusion evaporation channel using a Ni -58 beam on a Pd-102 target. The measured decay properties are E-p = 1765(1 0) keV and t(1/2) = 12(-3)(+4) mu s. Spin and parity J(pi) = 11/2(-) and a spectroscopic factor S-p(exp) = 0.58(-0.15)(+0.20) characterize the decayin g state.
