Abstract:

The \(\) resonances of atomic Lu have been investigated by photoelectron and photoion spectroscopy using monochromatized synchrotron radiation in the vacuum ultraviolet energy region. The total photoion yield has been compared to calculations in which the extended Fano theory (Mies formalism) and the Hartree-Fock method were applied. The resonance structure is dominated by the spin-orbit splitting of the 5p core hole. In the photoion yield spectra of singly and doubly charged ions a high fraction of Lu2+ ions has been found in the region of the 5p -1 (2P 1/2 )nd resonances. Photoelectron spectra, recorded in this resonance region, have been investigated with respect to deexcitation channels connected with Lu2+ ions. The 5p -1 (2P 1/2 )nd resonances predominantly autoionize by spin-flip into \(\) states, which decay in the second step into Lu2+ final ionic states.
