Two-photon double ionization of the H2 molecule: Cross sections and amplitude analysis

We perform time-dependent calculations of triply differential cross sections (TDCS) of two-photon double-electron ionization of the aligned H 2 molecule. Our TDCS results for equal energy sharing between photoelectrons agree quite well with a recent time-dependent calculation by Guan who employed a slightly different numerical technique. We supplement these studies by calculating TDCS at an unequal energy sharing and by generating symmetrized ionization amplitudes
