Methods of charge-state analysis of fast ions inside matter based on their X-ray spectral distribution

摘要

The X-ray spectral distribution of swift heavy Ti and Ni ions (11 MeV/u) observed inside aerogels (rho = 0.1 g/cm(3)) and dense solids (quartz, rho = 2.23 g/cm(3)) indicates a strong presence of simultaneous 3-5 charge states with one K-hole. We show that the theoretical analysis can be split into two tasks: first, the treatment of complex autoionizing states together with the originating spectral distribution, and, second, a charge-state distribution model. Involving the generalized line profile function theory, we discuss attempts to couple charge-state distributions. [References: 5]
