摘要：
Sequential two-photon double ionization of Kr atoms is theoretically considered. The angular distribution of emitted electrons is calculated with the dipole amplitudes evaluated within the multiconfigurational Hartree-Fock and Dirac-Fock approaches. The difference in angular distributions for two-photon and single-photon ionization is discussed.
