Abstract

The mechanisms of electronic energy loss in the process of incident particles interaction with Si and Al₂O₃at proper energies are investigated. The contribution to the electronic energy loss from highorder corrections， such as the relativistic correction， the shell correction， the density correction, the Barkaseffect correction and the Bloch effect correction are discussed respectively. It is found that the shell correction， the Barkaseffect correction and the Blocheffect correction are important at low energies， the relativistic correction and the density correction are important at high energies. The calculated results with these higherorder corrections are in good agreement with the experiment data (ICRU49).
