Photoelectron Spin-Polarisation Spectroscopy in the 5s5p2-Autoionisation Region of Indium

Photoelectron spin-polarisation measurements of In(5s2 5p) 2P,12 were performed in the autoionisation region of the 5s5p2-configuration using monochromatic circularly polarised synchrotron radiation at the electron storage ring BESSY. The autoionising levels are analysed in terms of partial cross section, dipole matrix elements and phase-shift differences. In addition the measured photoelectron spin-polarisation data were used for an independent check for the assignments of the autoionising levels.
