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 Numerical calculations have been done using a modified dwba1 fortran computer program which was originally made for hydrogen atom.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.


Keywords :

Autoionization; total cross section; negative ion resonances; absorption potential; distorted wave method.
