摘要：

Experimental and theoretical methods were used to study the formation of hollow atoms during the interaction of Ar17+ projectiles with a Si(lll) surface. Electron spectra were taken in a wide range of projectile energies from 17 eV to 170 keV. Peak structures due to K- and L-Auger electrons were found to vary significantly with the projectile energy. The angular dependence of the Auger electron intensities were interpreted by means of model calculations yielding information about the decay depth of the hollow atoms within the first layers of the surface.
