Exchange in low-energy e-CO/sub 2/ collisions

Journal Article · · Phys. Rev. A; (United States)
The validity of three approximate treatments of the exchange interaction in low-energy e-CO/sub 2/ scattering is assessed by comparing approximate and exact static-exchange eigenphase sums in the resonant Pi/sub u/ symmetry and the nonresonant ..sigma../sub g/ and ..sigma../sub u/ symmetries. Of the approximations studied: orthogonalized static, free-electron-gas model potential, and orthogonalized model potential: the latter has yielded results in best agreement with those of the exact treatment of exchange. Newly calculated static-exchange-polarization cross sections for energies from 0.1 to 2.0 eV are presented.
