  We confirm the results of previous works that the internal motion of quarks
inside charmonium mesons increases the cross section of the process $e^+e^-\to
$J/\psi\eta_c$. We also show, that this effect increases the widths of the
scalar meson decay into two vector ones and state that the decays
$\chi_{b0,2}\to2J/\psi$ can be used to detect these scalar mesons at Tevatron
and LHC colliders.
