摘要：

A determination of the angular distributions, beta, and relative partial photoionization cross sections, sigma, of the valence satellite lines of atomic scandium in the region of the 3p -> nd, ms excitations has been carried out using electron spectrometry in conjunction with monochromatized synchrotron radiation. This work is complementary to our earlier study of the partial cross sections of the Sc valence satellites but now includes angular distribution measurements of the most intense satellite lines. A correct theoretical 66 description of the experimental satellite sigma and beta values presented herein should help in rectifying present discrepancies between theory and experiment for the 3d and 4s mainline sigma and beta values.
