Abstract: In the framework of potential models for heavy quarkonium, the mass spectrum for the system ( bc) is considered. In particular, the spin-dependent splittings of S and P energy levels caused by spin-spin, spin-orbital and tensor interactions in the framework of the Breit-Fermi quasi-relativistic approximation with the screened quark interaction potential are calculated. The dependence of the energy splitting on the parameters of the interaction potential between the quarks is investigated. The calculated energy levels of the system bc can be used for experimental search for Bc mesons.
