  We investigate a contribution of the $d$ wave to the cross section of
$e^+e^-$ annihilation to the pair of charged leptons or nucleons close to
threshold of the process. In contrast to the point of view accepted in
literature, due to the Coulomb final state interaction this contribution does
not vanish even at zero relative velocity of produced particles. This results
in the nonzero asymmetry in angular distribution at threshold. Though value of
the asymmetry is small, observation of this effect is not hopeless.
