ABSTRACT
We have observed Auger electrons from doubly excited He[sup **](nln[sup ′]l[sup ′]), n=2, 3, and 4, produced by the double-electron transfer processes in the collisions between He[sup 2+] and alkaline earth atoms. From these results, we see that highly excited states such as (4lnl[sup ′]) states can be produced by the double-electron transfer collisions between He[sup 2+] and alkaline-earth atoms. Relative population of such states increased as the target atomic number increased. The mechanism of the two electron transfer processes is discussed by using potential curves. © 2000 American Institute of Physics.
