General Comments:

Levels: 1977LiYX and 1990Li46 suggest strong coriolis coupling among parity doublet bands, Kπ=1/2|+ and 3/2|+. See 1977LiYX for levels calculated including couplings between 1/2[541], 3/2[521] and 3/2[532] bands, and for amplitudes of each state in these bands. See 1988Le13 for energies of states calculated in a model by coupling a deformed shell model including octupole deformation to a reflection-asymmetric rotor core. See 1992Kv03 for intrepretation of levels in terms of quasipartice plus phonon model.

Jπ(level): From band assignments, model calculations (1992Kv03), and α decay (2003Ku44), unless given explicitly.

E(γ): From 225Ac α decay and 221Rn β- decay.

I(γ): Relative photon intensity deexciting each level, adopted from 225Ac α decay and 221Rn β- decay.

Limit on %β- was determined from absence of 221Ra α groups in the decay of 221Fr (1964Va20). 14C decay observed by 1994Bo28, 1986Ba26,1985Pr01. See 1989Ci03, 1988Sh29, 1988Bl11, 1987Sh04, 1987Po08, 1986Ir01,1986Gr20 and 1990Sh01 for calculations of partial T1/2(14C); see 1986Po06 for calculations of decay rates by 14C, 12C, 8Be, 15N, 13C, 11B, 16O and 15C emission.
