X-ray emission from multicharged ions interacting with solids

Abstract Systematic studies of X-ray emission in the interaction of various slow multicharged ions (MCI) with metallic surfaces were performed at various energies. A low resolution/high efficiency Si(Li) detector and a high resolution X-ray spectrometer have been used to detect the X-ray emitted by the ions. The results allow one to differentiate between X-rays emitted from the bulk (ion bulk interaction (IBI)) and from ions experiencing an interaction above the surface (ion surface interaction (ISI)). Another example for IBI at “high” vertical velocity is the observation of two electron-one photon double K α (or K αα ) emission with low energy MCI.
