Influence of partial ionization on the energy loss of fast ions in high-Z material
Analytical and simple numerical calculations of the stopping power of partially ionised high-Z targets are presented. Up to now such calculations have been difficult, mainly because of the lack of precise average ionisation potentials of the target ions. The aim of this paper is to clarify the importance of a suitable treatment of target ions in different ionisation stages and to show, by means of general scaling laws and explicit examples, that high-Z plasmas of high density and low ionisation degree may have smaller stopping powers than cold matter. The resulting range lengthening of the projectile ions might be of crucial importance for a proper design of pellets in inertial confinement fusion.
