摘要：

The new proton radioactivity Bi-185m has been observed, produced via the Mo-95(Mo-92,pn)Bi-185 reaction. Its decay proceeds from the low-lying 1/2(+) intruder state in Bi-185 to th, Pb-184 ground state with the emission of a proton of energy 1.585 +/- 0.009 MeV and a half-life of 44 +/- 16 mu s. This marks the first observation of proton radioactivity above the Z = 82 closed shell, and it has been used to obtain the admixture of a 0(+) intruder state in Pb-184 into the Pb-184 ground-state wave function.
