  We report a new analysis of double charmonium production in e+ e-
annihilation using a data sample collected by the Belle experiment. We confirm
our previous observation of the processes e+ e- -> J/psi eta_c (chi_c0,
eta_c(2S)) and perform an angular analysis for these processes. Processes of
the type e+ e- -> psi(2S) (c cbar)_resonant are observed for the first time. We
also observe a new charmonium state - X(3940), produced in the process e+ e- ->
J/psi X(3940).
