The cross section of the processis measured at center-of-mass (c.m.) energies fromto 4.600 GeV using data samples corresponding to a total integrated luminosity ofcollected with the BESIII detector operating at the BEPCII storage ring. The dependence of the cross section onshows an enhancement around 4.2 GeV. While the shape of the cross section cannot be fully explained with a singleorstate, a coherent sum of the two states does provide a reasonable description of the data.
