Dynamical And Collisional Approaches To The Transport Of Core And Rydberg Projectile States In Solids

Experimental studies of the production and transport of projectile excited states in solid carbon targets have been performed for Ar17+ and Kr35+ at high velocity (respectively v(p)=23 and 35.6 a.u.). A range of target thicknesses from single collision condition to equilibrium has been investigated. Charge state distributions, nl populations of core and Rydberg projectile states, as well as the population of fine structure substates (nl(J)) are determined. Theoretical predictions have been developed both in a collisional and a dynamical screening picture, using quantum as well as classical descriptions for the transport of projectile excited states. Discussions based on a comparison between experimental results and the different types of calculations are presented.
