The production of Ne K Auger electrons is investigated in fast heavy-ion--atom collisions with the use of a Ne gas target and Ne/sup n/+ and Ar/sup n/+ ions ranging in energy from 3 MeV/amu to about 15 MeV/amu. In particular, the projectile energy dependence of multiple L-shell ionization in Ne is compared to previous results from heavy-ion--atom collisions covering a projectile energy range from 1.2 MeV/amu to about 3 MeV/amu with atomic numbers varying between 8 and 18. The proposed linear relationship between the mean number of multiple ionized outer-shell electrons and the centroid energy of the corresponding Auger spectra is confirmed. The scaling behavior of the multiple ionization in Ne as a function of projectile energy and atomic number is investigated. It is found that the degree of multiple outer-shell ionization can be represented by a universal curve over a wide range of projectile energy and species.
