英文摘要	Lots of charmonium-like structures have been observed in the last two decades. Most of them have quantum numbers that can be formed by a pair of charm and anticharm quarks, thus it is difficult to unambiguously identify the exotic ones among them. In this Letter, by exploiting heavy quark spin symmetry, we present a robust prediction of the hadronic molecular scenario, where the psi(4230), psi(4360) and psi(4415) are identified as D over bar D-1, D* neutral charmonium-like exotic state with quantum numbers JPC = 0(--), denoted as psi 0(4360), should exist as a D* over bar D-1, and D* over bar D-2* bound states, respectively. We show that a flavor - over bar D-1 bound state. The mass and width of the psi 0(4360) are predicted to be (4366 +/- 18) MeV and less than 10 MeV, respectively. The psi 0(4360) is significant in two folds: no 0(--) hadron has been observed so far, and a study of this state will enlighten the understanding of the mysterious vector mesons between 4.2 and 4.5 GeV, as well as the nature of previously observed exotic Z(c) and P(c )states. We propose that such an exotic state can be searched for in e(+)e(-) -> eta psi(0)(4360) and uniquely identified by measuring the angular distribution of the outgoing eta meson.
