Proton and {alpha} radioactivity of {sup 185}Bi.
Proton and {alpha} emission from {sup 185}Bi have been confirmed and measured with improved statistics. The {sup 185}Bi nuclei were produced via the {sup 95}Mo({sup 92}Mo,pn) reaction at a bombarding energy of 420 MeV. The proton decay energy from the 1/2{sup +} intruder state in {sup 185}Bi to the {sup 184}Pb ground state was measured to be 1.598(16) MeV with a proton branching ratio b{sub p}=0.85(6). An {alpha} decay branch from the same state was measured, b{sub {alpha}}=0.15(6), with an energy of 8.08(3) MeV. The state has a half-life of 50(8) {mu}s. In addition, the {alpha} branching ratio of the ground state of {sup 184}Pb was determined for the first time to be b{sub {alpha}}=0.23(14).
