主　　题：resonant state one boson exchange model complex scaling method 

摘      要：Theorists have given various explanations for the discovery of Y(4630).We find that if Y(4630)is inter-preted as the D-wave resonant state of the ∧_(c)∧_(c)。system,the particle mass,decay width,and all quantum numbers are consistent with experimental *** use the Bonn approximation to obtain the interaction potential of the one boson exchange ***,we extend the complex scaling method to calculate the bound and resonant *** results indicate that the ∧_(c)∧_(c) system can form not only the bound state of the S wave but also the reson-ant state of the high angular momentum,and the ^(3)D_(1) wave resonant state can explain the structure of Y(4630)very Well.
