Abstract

Energy spectra of electrons ejected in the forward direction from 75-keV/amu He0-He,Ar collisions have been measured in coincidence with the charge-state-selected outgoing projectiles He0, He+, and He2+. The appearance of the cusp-shaped peak in the electron spectrum in coincidence with He0 gives the first clear experimental evidence that electron capture into the continuum states (ECC) occurs in collisions where the projectile is a neutral atom. The ECC for He0 impact is characterized by a considerably smaller width of the cusp peak than for He+ impact.
