We report an analysis of the _0b! _+c _−_+_− decay in a
data sample collected by the CDF II detector at the Fermilab Tevatron
corresponding to 2.4 fb−1 of integrated luminosity. We reconstruct
the currently largest samples of the decay modes _0b! _c(2595)+_−
(with _c(2595)+ ! _+c _+_−),_0b! _c(2625)+_− (with _c(2625)+
! _+c _+_−), _0b! _c(2455)++_−_− (with _c(2455)++ !_+c _+),
and _0b! _c(2455)0_+_− (with _c(2455)0 ! _+c _−) and measure
the branching fractions relative to the _0b! _+c _− branching
fraction. We measure the ratio B(_0b! _+c _−_+_−)/B(_0b!_+c _−) =
3.04 ± 0.33(stat)+0.70−0.55(syst) which is used to derive B(_0b! _+c
_−_+_−) = (26.8+11.9−11.2) ×10−3.
