Abstract

Autodetachment via the collisionally populated (1s2p2p)4Pe shape resonance of He- has been observed by means of 0°electron spectroscopy in a measurement of the double-differential cross section for single and double electron loss to the continuum in He- on Ar collisions at 75-keV/u projectile energy. An alternative parametrization has been developed for the autodetachment lines emitted with low energy in the projectile reference frame. The determined position and width of the shape resonance are in agreement with the results of theoretical calculations and photodetachment measurements.
