摘要：
We present a numerical study on the influence of Pauli's exclusion principle in the double ionization of helium in strong laser fields. To this end, we compare the ionization dynamics of the helium in its triplet and singlet configurations. The symmetric character of the electronic orbital wave-function affects strongly the mechanism of ionization in helium. In particular, it is found that the double ionization is partially suppressed in the ortho-helium case. The mechanisms relevant for this suppression are discussed.
