摘 要：The angular distribution and polarization of the x-ray photoemission of highly charged helium-like ions is studied following the K-LL dielectronic recombination of initially hydrogen-like *** is carried out within the framework of the density matrix theory combined with the multiconfiguration Dirac-Fock *** is paid to magnetic sublevel alignment in the resonant intermediate state and to its nonuniform radiative decay *** is shown that the Breit interaction between the incident and target electrons plays a significant role for the alignment of the resonant state and thus causes a substantial change in the x-ray emission characteristic,when compared to the incorporation of only the(non-relativistic)Coulomb *** most prominent difference in alignment parameter is found in the 2s2p_(1/2) J=1 resonant state for a wide range of atomic numbers from 9 to *** this resonant state of helium-like ions,the Breit interaction becomes significant for ions with nuclear charge Z~30 already.
