Experimental studies of the production and transport of projectile excited states in solid carbon targets have been performed for Ar[sup 17+] and Kr[sup 35+] at high velocity (respectively v[sub p]=23 and 35.6 a.u.). A range of target thickness 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[sub 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. © 2000 American Institute of Physics.

    It is shown that the Gilvarry distribution offers a good description of cumulative distributions of the number and volume (mass) of fragments as functions of the linear size, area, or mass of the fragments, which are obtained in experiments on dynamic fragmentation of brittle and ductile solids.
