Abstract

The energy spectrum of electrons emitted in the single-electron detachment process in collisions of 200-keV [Formula Presented] ions with He was measured. Taking advantage of the method of the 0° electron spectroscopy carried out with good angular and energy resolution, the lines from the decay of the ([Formula Presented]) [Formula Presented] shape resonance of [Formula Presented] were resolved, and the absence of the characteristic cusp peak in the double-differential cross section was established.
