General Comments:

Calculations, compilations:

Delayed neutron emission: 1989Br25

Favored α decay: 1992Bu03, 1993Bu09

Ground state properties: 1997Mo25, 1995Mo29

g.s. and excited state configurations: 1995Ci09, 1995Du05

Heavy ion emission: 1991Bl07, 1985Po11

Deformation, pairing gap, single-particle energies: 2005Pa73

2003Be41: Skyrme mean-field, levels, Jπ

2003Af02: Cranked relativistic Hartree-Bogoliubov theory, s.p. energies, deformation, pairing.

Single-particle Nilsson levels: 2011Ad15, 2009Mi02, 2006Af03, 2005Pa73, 1994Cw02.

1994Cw02 calculated the following single-particle level sequence: g.s. 1/2[620], 0.12 MeV 3/2[622], 0.18 MeV 7/2[613], 0.37 MeV 11/2[725], 0.42 MeV 9/2[734], 0.77 MeV 9/2[615].

Q(α), T1/2: 2009Sa25, 2009Zh39, 20008Bi10.

Measured α(θ): 2011Gu11, 2005Se08.

Levels: The level scheme and band assignments are from 255Fm α-decay (2005Ah09,1971Ah01,1975Ah01) and from 250Cf(d,p) (1990Ah02). For a discussion of single-particle Nilsson states above n=152, see 1990Ah02.

Gammas: All γ data are from 255Fm α decay.
