We study an elect,rot-phonon umodel xvith on-site Cotrlonab repulsions U.. at half filling byexact diagonalization combined with a mean-field approximation which gives accurate results inthe narrow-bandwidth case. Stmpercondtrctivity xvith off-site pairing is found to exist with aninverse isotope effect if and only if the phonon-rrtediated attraction is almost offset by U...
