Abstract

Electrons emitted in collisions of the bare ions He2+ and Li3+ with molecular hydrogen are detected and measured with a cylindrical mirror analyser (CMA). The projectile energy range covered extended from 5 keV/amu to 10.7 keV/amu for He2+ and from 2.6 keV/amu to 4.3 keV/amu for Li3+. The electrons observed are found to originate from autoionization of doubly-excited states Heo** (nln ‘1’ ) and Li+** (nln ‘1’) with n=2. n ≥2 populated by double-electron capture in a single collision.
