Popis:	The contribution of bulk electron crystal states to the ultraviolet photoelectron spectra (UPS) is studied for the following 4d-metals: molybdenum, rhodium, palladium, and silver. The discrepancy between the calculated curves of bulk contribution to the UPS and the experimental UPS curves is found to increase, when going from the elements at the end of 4d-period to the elements closer to its beginning. This regularity appears to be connected with the decrease in the d-electron localization in the above-mentioned sequence of elements, which is demonstrated by the calculations. Comparison of the calculated bulk contribution to the UPS with the experimental UPS allows to distinguish those peaks in the UPS of molybdenum and rhodium, which are most likely due to the surface electronic structure.
