In this work, we investigate the hidden charm decays properties of Y(4626), where Y(4626) is assigned as a S-wave Ds*+Ds1(2536)- molecular state with JPC=1--. The partial widths of the processes Y(4626)→ J/ψη, J/ψη′, ηcϕ, and χcJϕ, (J=\0,1,2\) are estimated by employing the effective Lagrangian approach. The present estimations indicate that the partial widths of the J/ψη and J/ψη^′ channels are of the order of 1 MeV, while the one of χc1ϕ is of the order of 0.1 MeV. Thus, we propose to further examine the molecular interpretation of Y(4626) by searching it in the cross sections for the e+e-→ J/ψη(′) processes, which should be accessible by the BES III and Belle II.
