Abstract

Measurements were made, at various emission angles, of energy spectra of electrons from Al induced by grazing-angle-incident ions of N6+, Ar12+, and Xe27+ with equal velocities corresponding to 0.98 MeV/amu. A new line which could not be explained by any of the hitherto identified mechanisms was observed at an energy obviously larger than that of an electron with a velocity equal to the projectile. The projectile and emission angle dependencies of the line are consistent with the dynamic image potential acceleration mechanism.
