摘　　要：We calculate the production of χ_c and η_c by the two-photon process in ultra-peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies. The differential cross section of transverse momentum distribution and rapidity distribution for (H = χ_c and η_c), are estimated by using the equivalent photon flux in the impact parameter space. The numerical results indicate that the study of χ_c and η_c in ultra-peripheral heavy ion collisions are feasible at RHIC and LHC energies.We calculate the production of χ_c and η_c by the two-photon process in ultra-peripheral heavy ion collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies.
