Abstract:

We examine the spectra corresponding to the secondary-electron bremsstrahlung produced by heavy ions penetrating thin solid foils. By using the Thompson approximation to describe the ionization process, and some other high-energy approximations, we develop a simple closed form, from which very useful information on the process can be obtained. A method results for reducing experimental data in a comprehensive way. The emerging universal shape function is compared with scaled experimental results, and the agreement is very satisfactory. © 1989 The American Physical Society.
