  The model of the $\chi_{c_i}-\gamma^*-\gamma^*$ and
$\chi_{c_i}-J/\psi^*-\gamma^*$ form factors developed in [1] for $\chi_{c_1}$
and $\chi_{c_2}$ is extended to $\chi_{c_0}$ case. The studies performed within
this model have shown that at BELLE II it will be possible to study in detail
$\chi_{c_i}-\gamma^*-\gamma$ form factors through measurements of the reaction
$e^+e^-\to e^+e^- \chi_{c_i} (\to J/\psi (\to \mu^+\mu^-)\gamma)$.The results
were obtained using the newly updated Monte Carlo generator EKHARA.
