Effect of Foil Thickness on Excited States in the Beam-foil Interactions

Abstract

The present communication reports experimental studies on the interaction mechanism of excited states, produced by fast heavy ions passing through carbon foil, with a thin carbon foil. Oscillatory structure of the lifetime spectrum of the combined peak of M1 and M2 decays in He-like Ti-ions gives a direct evidence of the transitions between 1s2p ³P₂ and 1s2s ³S₁ states on every collision.
