The Lorentzian lifetime widths of the 4d and 4f levels in the sixth-period elements /sup 74/W to /sup 83/Bi have been measured using photoelectron spectroscopy. A compilation of 4f-level widths from the literature is also made. The general trend of the 4f-level widths is well reproduced by McGuire's calculations, although the absolute widths seem to be underestimated. The 4d/sub 5/2/-level width shows a remarkable constancy over the whole series of elements and it varies only between 3.6 and 4.0 eV for all the investigated elements. The determined 4d level widths are well reproduced by recent calculations by Ohno and Wendin. Special attention has been paid to lifetime broadenings which are characteristic for the solid phase. Such broadenings are observed for the 4d/sub 3/2/ level due to N/sub 4/N/sub 5/O/sub 45/ Coster-Kronig processes. In the 4f shell a small Coster-Kronig broadening is also observed in the beginning of the series.
