Reference: 2012WA38

General Comments:

Produced by 204Pb(50Ti,n), E=4.68 MeV/α; 14 events with T1/2=48 μs and 8 events with T1/2=11 ms observed (1997He29).

Calculations, compilations:

g.s. properties: 1997Mo25, 1995Mo29, 2005Pa73

Single-particle Nilsson levels: 1994Cw02, 2005Pa73

1994Cw02 have calculated the following single-particle level sequence: g.s. 7/2[624], 0.02 MeV 9/2[734], 0.21 MeV 5/2[622]

2005Pa73 have calculated the following single-particle level sequence: g.s. 9/2[734], 0.01 MeV 7/2[624], 0.07 MeV 5/2[622],0.33 MeV 1/2[633], 0.38 MeV 1/2[501]

2005Re16: Calculated g.s. SF half-life.

2005Zu02: Calculated evaporation cross-section, survival probabilities.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Estimated ΔS(p)=520, ΔQ(α)=300 (2003Au03)
