Abstract.

The strong decay amplitudes and radiative partial widths of orbital and radially excited states of B and Bs mesons are presented. These results are obtained with a nonrelativistic potential quark model, the nonrelativistic reduction of the electromagnetic transition operator, and the 3P0 model of strong decays. The predictions are compared to experiment where possible and assignments for the recently discovered states, \(B_{1}(5721)\), \( B_{2}^{\ast}(5747)\), \(B_{J}(5840)\), \(B_{J}(5970)\), \(B_{s1}(5830)\), and \(B_{s2}^{\ast}(5840)\), are made.
