| Popis: | In the present paper , we have tabulate the screening parametersη_(screening ) and the differential cross section of Mott scattering〖dσ〗_Mott/〖dσ〗_Rutherford by Aluminum nucleus in the energy range(10-0.005)MeV and angles by employing Mackinely-Fashbach equation as well as we have calculate the ratio 〖dσ〗_Mott/〖dσ〗_Rutherford For the energy range (50-350)MeV for the same angles, by using the improved Rutherford equation .All these equation written with Visual Basic program 2012.By comparing the obtained results with the available one, we found that the factor η_(screening )proportional with the incident electron energy, which influences the screening process of the orbital electrons by the atomic nucleus ,thus lowering the Bremsstrahlung probability cross section, while the values of 〖dσ〗_Mott/〖dσ〗_Rutherford with Mackinely-Fashbach equation, are in good agreement with the compared values ,and the cross section obtained by improved Rutherford equation ,shows that the effect of recoiling term is the biggest in comparison to other correction factors. |
