The method of Auger electron spectroscopy was utilized to measure cross sections for the production of {ital K}-Auger electrons in N{sup 7+}+Ne and N{sup 6+}+Ne collisions at an impact energy of 35 keV. In addition to the {ital K}-Auger electrons from the nitrogen projectile following multiple electron capture, {ital K}-Auger electrons of the Ne target are observed for the system N{sup 7+}+Ne. This observation is attributed to dielectronic excitation, produced by electron-electron interaction, where a {ital K}- and an {ital L}-shell electron of Ne are transferred into the {ital K} shell of N{sup 7+}. {copyright} {ital 1996 The American Physical Society.}
