Abstract

We argue that an experimental search for an ηc\eta_c', the first radial excitation of the ηc(2980)\eta_c(2980), may be carried out using the two photon process e+ee+eγγ\rae+eηce^+e^- \to e^+e^- \gamma \gamma \ra e^+e^-\eta_c'. We estimate the partial width Γγγ(ηc)\Gamma_{\gamma \gamma}(\eta_c') and the branching fraction B(ηch)B(\eta_c' \to h), where hh is an exclusive hadronic channel, and find that for h=KsoK±πh = K^o_s K^\pm \pi^\mp it may be possible to observe this state in two photon collisions at CLEO-II.
