Abstract
Using a Q-QBAR potential with the color screening effect due to the cr eation of light quark pairs. the spectra of bbBAR and ccBAR systems ar e calculated. An improved fit for the masses of the highly excited sta tes can be obtained. In particular. the psi (4160) might be assigned a s the 4S ccBAR state.
