Schiwietz, G.; Grande, P.L.: Extending the CasP energy-loss theory to low velocities. In: 20th Ion-Surface Interactions Conference 25 - 29 August 2011, Zvenigorod, Russia : ISI-2011. Book of Reports of ..... Moskva: Nauka, 2011, p. 43-49

A review on recent developments in the theoretical treatment of electronic energy losses of bare and screened ions in solids and gases is presented. Specifically, the UCA (unitary convolution approximation) stopping-power model has proven its strengths for the determination of non-equilibrium effects for light as well as heavy projectiles at intermediate to high projectile velocities. The focus of this contribution will be on the UCA and its extension to specific projectile energies far below 100 keV/u.
