    "abstract": "We experimentally demonstrate and systematically study the stimulated revival\n(echo) of motional wave packet oscillations. For this purpose, we prepare wave\npackets in an optical lattice by non-adiabatically shifting the potential and\nstimulate their reoccurence by a second shift after a variable time delay. This\ntechnique, analogous to spin echoes, enables one even in the presence of strong\ndephasing to determine the coherence time of the wave packets. We find that for\nstrongly bound atoms it is comparable to the cooling time and much longer than\nthe inverse of the photon scattering rate.",
