I've always wondered about the explanation that the Mossbauer effect occurs because the lattice as a whole absorbs the recoil energy. This case seems indistinguishable from the one where the nucleus is vibrating back and forth horizontally and emits the photon as it is moving forward, in the direction of travel, causing the recoil to cancel. Is anyone familiar enough with the Mossbauer effect to explain why this alternative explanation is ruled out? Eric
