Research Abstract

When the fast heavy atomic ions pass through the periodic structure of a single crystal, the ions have a chance to be resonantly excited by feeling the time-dependent oscillating electric field, which is called resonant coherent excitation. The electronic transition between the atomic levels corresponding to the X ray regions is feasible for several tens GeV heavy ions. The present research on this process demonstrated quantum states manipulation without using photon, and a new possibility for high precision spectroscopy is exploited.
