A comparison of core state populations of initially bare Kr36+ ions emerging from gazeous and solid targets is presented. A new important feature of this experiment lies in the fact that for such fast heavy ions, the single collision condition is fulfilled even in solid targets. Our results are analyzed in the framework of two alternative models : multicollision processes including nt-nk' intrashell excitation, or collective response of the medium inducing Stark mixing of the substates in a solid. Our results favor the second one, and may enlighten previous results on excited populations in Rydberg states at the exit of solid foils. Other consequences such as possible future coherence angle and field strength measurements are considered.
