In this paper the production of excited vector and pseudoscalar charmonium mesons in annihilation is analyzed in the framework of light cone. In particular the cross sections → ψ(2S)ηc(1S), ψ(1S)ηc(2S),ψ(2S)ηc(2S) have been calculated. It is shown, that contrary to NRQCD the cross sections calculated in the framework of light cone agree with experimental data.
