Query: Signatures of Strong Momentum Localization via Translational-Internal
  Entanglement   We show that atoms or molecules subject to fields that couple their internal
and translational (momentum) states may undergo a crossover from randomization
(diffusion) to strong localization (sharpening) of their momentum distribution.
The predicted crossover should be manifest by a drastic change of the
interference pattern as a function of the coupling fields.
