The smoothing properties of Schro dinger semigroups, e &tH , H= & 1 2 2+V, on the scale of Bessel potential spaces L p, : are studied. We strengthen the (L p &L p, : )smoothing theorem due to M. A. Kon and the author. The new version of this theorem contains a sharp time-estimate for the norm of the
