The complex polarization potential of the (e,2e) reaction for electron-atom impact
电子碰撞原子(e,2e)反应的复极化势

In the paper, we study the influences of the complex polarization potential of the continued channel on the triplet differential cross section of the electron momentum spectroscopy. The complex polarization that are calculated by the coupled channel optical potential method was added to the distorting potentials in the distorted wave Born approximation. In the target Hartree-Fock approximation, we calculated the triple differential cross section (TDCS) of the (e,2e) reaction of 3p, 3s electron argon and 2p, 2s electron neon atom at the incident energies 1500eV and 200eV in the non-coplanar symmetric geometry and compared the theoretical results with the electron momentum spectroscopy (EMS) experimental data. The calculation results agree with the data of the EMS within experimental errors. The influence of polarization potentials at a high incidence energy is very small; but it becomes more notable at a low incidence energy.
