Adopting the assummation that the quark interaction is the sum of the usual one - gluon direct exchange and the mixture of linear scalar and vector potentials, we structure the relativistic corrections of order v2 / c2to the cornell potential, including the annihilation potential for the quark and antiquark of the same favors which plays the same role with the one - gluon direct exchange at short distances. the effects of the relativistic corrections on the hyperfine splittings of quarkonium states are discussed, and a good fit to the available experimental data is obtained on heavy quarkonium mass spectra
