摘要	The semileptonic decays B-c(+) P(V) + l(+) + (v) over bare and the nonleptonic decays B-c(+) -> P(V) + L, where P(V) denotes a pseudoscalar (vector) charmonium or (bs)-meson, and L denotes a light meson, are studied in the framework of improved instantaneous Bethe-Salpeter (BS) equation and the.Mandelstam formula. The numerical results (width and branching ratio of the decays) are presented in tables, and in order to compare conveniently, those obtained by other approaches are also put in the relevant tables. Based on the fact that the ratio BR(B-c(+) -> psi(2S)pi(+))/BR(B-c(+) -> J/psi pi(+)) = 0.24(-0.040)(+0.023) estimated here is in good agreement with the observation by LHCb BR(B-c(+) -> psi(2S)pi(+))/BR(B-c(+) -> J/psi pi(+)) = 0.250 +/- 0.068(stat) +/- 0.014(syst) +/- 0.006(B), one may conclude that with respect to the decays the present framework works quite well.
