摘要：

We apply the convergent close-coupling (CCC) formalism to the problem of two-photon double ionization of helium. The electron-photon interaction is treated perturbatively whereas the electron-electron interaction is included in full. The integrated two-photon double ionization cross-section is substantially below non-perturbative literature results. However, the pattern of the angular correlation in the two-electron continuum is remarkably close to the nonperturbative time-dependent close-coupling calculation of Hu et al (2005 J. Phys. B: At. Mol. Opt. Phys. 38 L35).
