The nuclear number(A) dependence of the back scattering J/psi (x_F<0) production cross section will provide important information for the existence of the intrinsic charm. I would like to perform Monte-Calro simulation to study the feasibility to measure A dependence of back scattering J/psi by using the E16 detector at J-PARC.
