Abstract:
In this paper the production of excited vector and pseudoscalar charmonium mesons in \epem annihilation is analyzed in the framework of light cone. In particular the cross sections \epem \to \psi(2S)\eta_c(1S), \psi(1S)\eta_c(2S),\psi(2S)\eta_c(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.- 13.25.Gv
