We calculate the spectra of charmonium and bottomium in an approximationscheme which treats hard gluons perturbatively while soft gluons are expandedin a set of localized wave functions. Quark-antiquark and quark-antiquark-gluonsectors are included. Reasonable agreement with 2 parameters only is found butthe spectra are too coulombic. Despite large coupling constant the admixture ofthe quark-antiquark-gluon sector is found to be remarkably small.
