Abstract
In the framework of sum rules with the use of the quarkonium mass spec trum, evaluated in the quasiclassical approximation, estimates are obt ained for the leptonic constant f(B)(stat) similar or equal to 320 +/- 60 MeV in the static limit and for the average heavy quark momentum s quared mu(p)i(2) similar or equal to 0.5 +/- 0.1 GeV2.
