General Comments:

Calculations, compilation:

α decay, deformation parameters: 1996St14, 1996St28

α decay, T1/2(α): 1993Bu09, 1992Bu03

Ground state properties: 1997Mo25, 1997Mo29

Pion decay: 1988Io05

Single-particle Nilsson levels: 2004Pa04, 1994Cw02

2004Pa04 calculate the following single-particle level sequence: 0.05 MeV 7/2[633], 0.25 MeV 5/2[642], 0.35 MeV 1/2[400], 0.51 MeV 3/2[402], 0.54 MeV 1/2[521]

1994Cw02 calculate the following single-particle level sequence: g.s. 3/2[521], 0.15 MeV 7/2[633], 0.34 MeV 5/2[642], 0.44 MeV 1/2[660], 0.63 MeV 3/2[651], 0.82 MeV 5/2[523]

Measured relative L and M x-ray intensities: 1990Po14

See 1975Er01 for rotational band assignments

Gammas: All γ data are from 253Es α decay, unless otherwise noted.

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

Q-value: 124.0 14 6300 syst 4832 5 5525.0 23 2009AuZZ,1995Au04

Q-value: Estimated ΔS(n)=71 (2011AuZZ)
