The integrated luminosity in the BELLE II experiment (20-50 ab$^{-1}$) will allow to access information never available before. It was found, within the model implemented in the newly updated Monte Carlo generator EKHARA, that at BELLE II it will be possible to study in detail $\chi_{ci} − \gamma^∗ − \gamma$ form factors through measurements of the reaction $e^+e^- \to e^+e^-\chi_{ci} (\to \gamma J/\psi (\to \mu^+ \mu^-))$. The proposed measurements will also serve as tests of the models predicting the $\chi_{c1}$ and $\chi_{c2}$ electronic widths.
