Show affiliationsA determination of the angular distributions and the relative partial photoionization cross sections of the 3d and 4s mainlines and the largest satellite line of atomic chromium in the region of the 3p → nd, ms excitations has been carried out using electron spectrometry in conjunction with monochromatized synchrotron radiation. We observe strong deviations of β from expected values of 2.0 for the 4s mainline at many of the 3p → nd, ms resonances. This indicates the importance of relativistic effects in the autoionization of this half-filled subshell atom. High resolution constant-ionic-state spectra are comparable with previous high resolution absorption measurements. A comparison of our 3d β values with recent spin-polarized random phase approximation calculations generally shows good accord with some exceptions.
