Impact Parameter Dependent Resonant Coherent Excitation of Relativistic Heavy Ions Planar Channeled in Crystals
ions has been observed through measurements of the surviving charge state of Arions planar channeled in a Si crystal. We experimentally demonstrate trajectory-dependent, i.e., impactparameter dependent resonant-coherent-excitation phenomena by measuring the energy deposition incoincidence with the charge state of emerging ions. The resonant-coherent-excitation transition energyreﬂects spin-orbit
