Abstract
We report on the momentum distribution line shapes for the quantum delta-ki cked rotor in the presence of environment induced decoherence. Experimental and numerical results are presented. In the experiment ultracold cesium at oms are subjected to a pulsed standing wave of near resonant light. Spontan eous scattering of photons destroys dynamical localization. For scattering rates used in our experiment the momentum distribution shapes remain essent ially exponential.
