摘要
A search for the production of the 0 c meson, the rst radial excitation of the ground state of charmonium c(2980), in the photon-photon fusion reaction at LEP has been performed using the data collected by the DELPHI detector during 1992-1996. No evidence of 0 c production is found in the mass region 3520{3800 MeV/c. An upper limit for the ratio of the two-photon widths of the 0 c and c is obtained. (Submitted to Physics Letters B)
