Abstract
Profiles of the autoionizing state in He have been observed in the ejected-electron spectrum of + He for small angles of ejection and for energies of 6 to 150 keV. The shape parameter shows an increasing dependence on projectile energy as the angle of ejection is decreased, with strong, quasiperiodic oscillations appearing at 10°.
