Abstract

Experimental results of measurements of the O7+ Rydberg yield after passage of 13–24 MeV oxygen ions through carbon foils of different thicknesses are presented. The data have been obtained by observing Rydberg states in the 58 < n < 75 range of main quantum numbers by means of RYDFISS, a method using field ionization and spatial separation techniques. For thin foils a significant increase of the O7+ Rydberg population with increasing thickness is observed, although this population was normalized to the O7+ exiting charge fraction. The equilibrium Rydberg yield A7 shows a pronounced dependence on the projectile velocity.
