In the framework of sum rules with a use of quarkonium mass spectrum,
evaluated in the quasiclassical approximation, estimates of leptonic constant
$f_B^{stat}\simeq 320\pm 60$ MeV in a static limit and for the average heavy
quark momentum squared $\mu_\pi^2 \simeq 0.5\pm 0.1$ GeV$^2$ are obtained.
