Hollow Atoms and Interactions of Highly Charged Ions with Surfaces
The interaction of highly charged particles (ions) with surfaces has been studied recently. The first experiments (1988) were mainly the study of the ejected electrons and the dynamics of the ions. The sputtering of the surface and the in-flight emission of the ion began in 1990. We present the methods and characteristics of the study of ion emissions using X-ray spectra during the approach and penetration of a surface. “Hollow atoms” formation and their “atomic clock” properties are described. Recent interesting results on interactions with Silicon lead to the “trampoline effect”.
