dc.description.abstractIn previous studies made on electron impact excitation of lowest autoionizing state of cesium atom, there are discrepancies in the results obtained using theoretical and experimental methods. Even the theoretical results do not agree among themselves. So in this study, differential cross sections, integral cross sections, alignment parameter and angular correlation parameter (lambda) for electron impact excitation of the lowest autoionizing state in cesium have been calculated using Distorted Wave Method with the new distortion potential. We have applied a linear combination of static potentials of the target taken in both initial and final states as the final channel distortion potential and static potential in the initial state as the initial channel distortion potential. The wave functions used in this model are the double zeta wave functions. Numerical calculations have been performed using a modified DWBA,l program. Comparison of the present results with the available theoretical and experimental results shows that the present integral cross sections results at low energies (≤ 40 eV) are in better agreement with the experimental results compared to other theoretical results. Lambda and alignment parameters results have the same trend as other theoretical results even though the differential cross section results are in disagreement with the other theoretical result.en_US
