摘要：

Recent high-energy (e,3e) experiments indicate that the one-step mechanism (shake-off process) is insufficient. We have performed an ab initio calculation that takes into account all the two-step mechanisms of double ionization. This calculation uses the second Born approximation and correlated wave functions for the initial bound state. We show that the two-step processes are not negligible and must be added to the one-step process with the production of interference terms.
