    "abstract": "We present here the results of calculations of photoelectrons\u0027 angular\nanisotropy and spin-polarization parameters for a number of semi-filled shell\natoms. We consider ionization of outer or in some cases next to the outer\nelectrons in a number of elements from I, V, and VI groups of the Periodic\nTable. All calculations are performed with account of multi-electron\ncorrelations in the frame of the Spin Polarized version of the Random Phase\nApproximation with Exchange - SP RPAE. We consider the dipole angular\ndistribution and spin polarization of photoelectrons from semi-filled subshells\nand from closed shells that are neighbors to the semi-filled shells. We have\nconsidered also angular anisotropy and spin-polarization of photoelectrons from\nsome excited atoms that are formed by spin-flip of one of the outer electrons.\nTo check the accuracy and consistency of the applied SP RPAE approach and to\nsee the role of the nuclear charge variation only, we have calculated the\ndipole angular anisotropy and spin-polarization parameters of 3p - electrons in\nK and compare them to Ar and K+ that have the same configuration. Entirely, we\nhave calculated the angular anisotropy and spin-polarization parameters for\nfollowing subshells of atoms N (2p), P (3p), Ar (3p), K+(3p), K(3p), Cr(3p,\n3d), Cr*(3d), Mn(3p, 3d), As(3d, 4p), Mo(4p, 4d), Mo*(4d), Tc(4p, 4d), Sb(4d,\n5p), Eu(4f). The peculiarities of obtained parameters as function of photon\nfrequencies are discussed, as well as some specific features of considered\nsemi-filled shell objects.",
