The partial photoionization cross-sections of the 4d-, 5p-, 4f- shells and the valence band of Ce, Pr, Nd, Eu and Gd are measured in the region of the 4d..-->..4f excitation. The sum is compared with the corresponding absorption spectrum in order to estimate the importance of different decay channels of the excited 4d/sup 9/4f/sup N+1/ configurations. For the heavy rare earth metals, which show a large 4f multiplet splitting, the authors demonstrate that the coupling of the 4f ionization to the 4d..-->..4f excitations strongly depends on the particular (4f/sup N-1/) /sup 2S+1/sub L/sub J/ - multiplet lines. This effect is also discussed for the 5p multiplet lines in Eu which arise from the coupling of the 5p hole with the 4f electrons. 26 references, 14 figures, 1 table.
