| Abstract | ||
| Energy Loss Function (ELF) of derived from optical limit and extended to the total part of momentum and their energy excitation region ELF plays an important function in calculating energy loss of electron in materials. The parameter Inelastic Mean Free Path (IMFP) is most important in quantitative surface sensitive electron spectroscopies, defined as the average distance that an electron with a given energy travels between successive inelastic collisions. The stopping cross section and single differential cross-section SDCS are also calculated and gives good agreement with previous work. | ||
