Abstract
A precision calculation of the two-photon detachment cross section for [Formula Presented] is performed by means of a non-Hermitian Floquet theory. A highly accurate initial state wave function is used along with fully correlated saddle-point wave functions for the intermediate and final states. The cross section is investigated for energies below the [Formula Presented] and [Formula Presented] thresholds. The peak cross section predicted for the [Formula Presented] resonance is [Formula Presented] [Formula Presented] sec at 10.873 2 eV. It represents an ab initio theoretical prediction in complete agreement with the experimental result of 3.2 [Formula Presented] [Formula Presented] sec at 10.873 2(27) eV. © 2000 The American Physical Society.
