Abstract

Using the CLEO-II detector at the CESR e⁺e^- storage ring running at the center-of-mass energy around 10.6 GeV, we have studied exclusive production of charmonium states in two-photon collisions. Employing a dataset comprising 3.0 \rm fb^-1 we have searched for decays of the η_c, χ_c0 and χ_c2 mesons resulting in four charged hadrons. We report on the measurements of the cross sections and two-photon widths of these charmonium states.
