ENHANCEMENT OF DIELECTRONIC PROCESSES IN NE10++HE COLLISIONS AT LOW KEV ENERGIES

The method of high-resolution Anger spectroscopy was used to study mec hanisms for double-electron capture producing the projectile configura tions 3lnl' and 4lnl' (n greater than or equal to 4) in Ne10+ + He col lisions. Emphasis was given to slow collisions with projectile energie s near I keV. At low collision energies the production of the configur ations 3lnl' (n greater than or equal to 6) of nonequivalent electrons is found to become dominant. It is shown that dielectronic processes produced by the electron-electron interaction play a major role in the creation of the Ne8+(3lnl') states.
