摘要：
We discuss the use of uncorrelated final state wave functions in calculations of double ionization processes. We show that in some physical situations such a simplified treatment can provide meaningful results. In particular, the prevalence of back-to-back emission in two-photon double ionization and even energy sharing between the photoelectrons make it possible to use uncorrelated final state wave functions for total integrated cross-section calculations.
