Proton decay of the closed neutron shell nucleus {sup 155}Ta

PDF Version Also Available for Download.

Description

The new proton radioactivity {sup 155}Ta has been observed. It was produced via the p4n fusion evaporation channel using a {sup 58}Ni beam on a {sup 102}Pd target. The measured decay properties were: E{sub p} = (1765 {+-} 10) keV and t{sub 1/2} = (12{sub {minus}3}{sup +4}) {micro}s. Using the WKB approximation a spin and parity of J{sup {pi}} = 11/2{sup 2{minus}} and a spectroscopic factor of S{sub p}{sup exp} = 0.58{sub {minus}0.17}{sup +0.22} were determined.
