| Abstract: | We have presented a method for the analysis of the inelastic scattering matrix elements between initial and final Alater orbital in Coulomb-eikonal approximation.By a parameter integral the inelastic scattering matrix elements have been decomposed into two parts:the target form factor and the projectile distorted ones.The former can be expressed analysis functions and the distorted factor can be calculated in non-partial-wave form,including the contribution from all partial wave.The relationship between the inelastic scattering matrix element and scattering angle using the generalized function for 1s-2s and 1s-3s at incident energy of 54.8eV and electron-impact excitations. |
