S(p)= -1580 keV SYQ(α)= 3940 keV SY
Reference: 2021Wa16

General Comments:

Experimental search:

2001Ma69: 64Zn(58Ni,p5n) E=325 MeV, recoil mass separator (FMA) with PPAC/DDSD detectors at focal plane. Proton radioactivity was not observed; deduced σ<5 nb for 20 μs<T1/2<20 ms.

Non observation could be explained by

i) proton decay with σ(p5n) below 5 nb

ii) Q(p) too large that will render T1/2<1 μs

iii) Q(p) too small, and thus β decay will be the dominant decay mode.

Theoretical works:

2020So24: S(p)=-1.09 MeV, T1/2(p)=6 μs

2019Mo01: S(p)=-0.80 MeV, T1/2(β)=0.12 s

2016Qi02: S(p)=-0.74 MeV, T1/2(p)= 4 μs

2001Go20: β2=0.31, β4=0.02, S(p)=-1.1 MeV

Q-value: ΔS(p)=380; ΔQ(α)=300 (2021Wa16)
