摘要: Based on our earlier paper, the momentum correlation of the four bodies in the final state is further considered for (e, 3e) processes on helium. A fivefold differential cross section (FDCS) for electron-impact double ionization of helium is calculated by use of the modified model for high incident energy (1-5.6keV). It has been found that the present results give a better description for the experimental data, as compared with the results of our earlier paper.
