Abstract / Description of output

The new proton radioactivity Bi has been observed, produced via the Mo(Mo,/Jw)Bi reaction. Its decay proceeds from the low-lying 1/2 intruder state in Bi to the Pb ground state with the emission of a proton of energy 1.585 ± 0.009 MeV and a half-life of 44 ± 16 μs. 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 into the Pb ground-state wave function.
