摘要：

A search for the production of the eta(c)' meson, the first radial excitation of the ground state of charmonium eta(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 eta(c)' production is found in the mass region 3520-3800 MeV/c(2). An upper limit for the ratio of the two-photon widths of the eta(c)' and eta(c) is obtained.
