Abstract
The results of recent VUV photoionization experiments of the 5d elemen ts Ta, W, Re, Ir and Pt using atomic beam technique, excitation with m onochromatized synchrotron radiation and detection of singly and doubl y charged photoions are discussed. Special attention is given to the r esonances caused by discrete transitions of the 5p and 4f electrons in to the unfilled 5d subshells. As there is a crossover of the 5p and 4f levels along the series of the 5d elements the result is a complicate d structure of the corresponding interacting resonances. The photoion spectra are compared with theoretical calculations carried out within the relativistic time dependent local density and the relativistic Har tree-Fock approximation.
