摘要：

We argue that an experimental search for an eta(c)', the first radial excitation of the eta(c)(2980), may be carried out using the two-photon process e(+)e(-) --> e(+)e(-)gamma gamma --> e(+)e(-)eta(c)'. We estimate the partial width Gamma(gamma gamma)(eta(c)') and the branching fraction B(eta(c)' --> h), where h is an exclusive hadronic channel, and find that for h = K(s)(0)K(+/-)pi(-/+) it may be possible to observe this state in two-photon collisions at CLEO-II.
