Abstract

Recent measurements of the Belle Collaboration of the exclusive production of two charmonia in the e⁺e^- annihilation differ substantially from theoretical predictions. Recently it was suggested that a significant part of this discrepancy can be explained by the process e²e^- --> 2J/psi and value for its cross-section was published. In this paper it is shown, that these results are incorrect and the values for the cross-sections of the production of different vector charmonia are presented.
