Abstract

A determination of the relative partial photoionization cross sections of the 3d and 4s main lines and associated 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. The superior resolution inherent in these measurements has revealed additional structure not previously seen in earlier experimental work, highlighting the rich and complex structure of this relatively simple open-shell atom. Relative intensities and binding energies of the 3p photolines are also reported. A comparison with recent many-body perturbation theory calculations in LS coupling shows only marginal agreement. Discrepancies between theory and experiment are thought to arise from the use of LS coupling and neglect of satellite channels in the calculation.
