  The mass spectrum of $c\bar{b}$ states has been obtained using the
phenomenological relativistic quark model (RQM) with coupled channel effects.
The Hamiltonian used in the investigation has confinement potential and
confined one gluon exchange potential (COGEP). In the frame work of RQM a study
of M1 and E1 radiative decays of $c\bar{b}$ states has been made. The weak
decay widths in the spectator quark approximation have been estimated. An
overall agreement is obtained with the experimental masses and decay widths.
