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 
resonances.
Photoelectron spectra, recorded in this resonance region, have been
investigated with respect to deexcitation channels connected with
Lu2+ ions.
The resonances predominantly autoionize by
spin-flip into 
states, which decay in the second
step into Lu2+ final ionic states.
