Abstract
The decay constant for the vector state of 3S-level in the heavy (bc)-quarkonium is evaluated in the framework of sum rules for the mesonic currents. A scaling relation for the constants of vector quarkonia with different quark contents is derived. The numerical estime gives Γ(Bc∗+(3S) → B+D0) = 90 ± 35 MeV.
