Abstract The rf electric resonance technique is discussed with special regard to its applicability to the analysis of excitation processes in ion-atom collisions. In particular, it is useful for investigating substate populations of excited Helium atoms and other He-like systems. A convenient set-up for the rf resonance circuit and interaction region is described. Within the frequency range 100 MHz≲ν≲1000 MHz, rf electric fieldsE 1≲100 V/cm were applied to He atoms excited by ion impact.E 1 can accurately be measured using level-crossing techniques, and thus a detailed analysis of the shapes and amplitudes of resonance signals becomes possible.
