Abstract

The hyperspherical R -matrix method with semiclassical outgoing waves introduced by us previously Phys. Rev. A 60 , 3667 (1999) is applied to the one-photon double ionization of the He atom. The absolute differential cross sections obtained are in excellent agreement with experiment for the very challenging dynamical situations considered. This method is the first one to compute the final double continuum state accurately over the entire configuration space, from the vicinity of the nucleus to the asymptotic region.
