Effect of Exchange and Absorption Potential in the Distorted Wave Calculation of Electron Impact Excitation of Auto Ionizing State of Rubidium

This Research of electron impact excitation of autoionizing states of rubidium have calculated the integral cross section using Distorted Wave Method in the range of incident energy of 15.8 -1000 eV. Numerical calculations have been done using a modified dwba1 fortran computer program which was originally made for hydrogen atom. The results are compared with Borovik work which showed a systematic agreement with inclusion of absorption potential, it also clear that incomparision with Pangantiwar and Srivastava there is a good qualitative agreement though the quantitave is attributed to the Multi Zeta Hartree fork wave functions applied.
