Abstract: One meson exchange potential of the KK system is studied.When momentum-squared terms are included, the one meson (ρ,ω,φ) exchange potential alone fails to produce any KK bound state. With the Coulomb potential, K+K－ can form atomic bound state---the kaonium. The influence of the one meson exchange potential on the ground state energy of kaonium and its decay widths to ππ and πη are evaluated.
