The processes $e^+ e^-\to J/ \Psi \chi_{c0}, \Psi(2S) \chi_{c0}$ at   $\sqrt s = 10.6$GeV in the framework of light cone formalism
  In this paper we have analyzed the production of pair charmonium mesons in the reactions $e^+ e^- \to J/ \Psi \chi_{c0}, e^+ e^-\to \Psi(2S) \chi_{c0}$ at energy $\sqrt s = 10.6$GeV in the framework of the light cone formalism. In comparison with NRQCD the numerical results for the cross sections are in better agreement with experiment.
