Abstract
We identify a parameter that controls the localization length in a driven quantum system. This parameter results from an additional quantum degree of freedom. The center-of-mass motion of a two-level ion stored in a Paul trap and interacting with a standing-wave laser field exhibits this phenomenon. We also discuss the influence of spontaneous emission.
