Abstract : The polarization potential for an electron in the field of an oxygen atom was determined by utilizing recent experimental results on the binding energy of 0(-). The corresponding polarization potential for atomic nitrogen was obtained from the results for oxygen by an extrapo lation based on the theory of polarization. From these results the photo cross section for 0(-) and the scattering cross section sections for oxygen and nitrogen were calculated. The photo cross section is in good agreement with experimental results. The scattering cross sections are compared with other recent calculations. It is also shown on the basis of the general theory of the photo cross section that the energy dependence of the cross section determines the scattering length for electron scattering. The agreement of the computed photo cross section with experiment therefore is a direct check on the scattering prediction. (Author)
