251CF c Production: {+249}Bk(|a,xn) and {+249}Bk({+3}He,xn), ion chem.
251CF2c Measured: E|g, I|g, |g|g, (Ge(Li), NaI(Tl)) (1970Ah01)
251CF c 2005Ah09: decay product of {+251}Fm. Measured ce, Si(Li), FWHM=1 at
251CF2c 100 keV; |g, Ge(Li).
251CF cL E$From 1970Ah01
251CF cL J$From adopted levels
251CF cE $1970Ah01 report that from I|g, I(K| x ray) and (|g)(K| x ray)
251CF2cE coincidences, |?65% of |e feeds the g.s. band. This I(|e), however,
251CF3cE does not produce agreement between the measured and calculated I(K| x
251CF4cE ray). From the measured I(K| x ray) the intensity of the |e to the
251CF5cE g.s. band is |?80%.
251CF cE IE$Deduced from intensity balance in the level scheme.
251CF cG $I(Cf K| x ray)=64% {I5} (2005Ah09), K| x ray/177.6|g=18 {I2} from
251CF2cG (K| x ray)(K| x ray,177.6|g) (1970Ah01)
251CF cG RI(D)$From ce(M) (2005Ah09) and |a(M) (Theory)
251CF cE $Decays depopulating the levels in the ground-state band were not
251CF2cE observed. The intensity and log {Ift} values associated with the
251CF3cE ground state given here should be understood to apply to the levels
251CF4cE of the ground-state band as a group.
