Using x-ray-photoelectron spectroscopy and bremsstrahlung-isochromat spectroscopy (BIS), we have studied the U/sub x-italic/Y/sub 1-//sub x-italic/B/sub 4/ system which shows a magnetic-nonmagnetic transition at x-italic = 0.6. Contrary to the conclusions from previous magnetic measurements, we find that the U 5f-italic exhibit itinerant nature for all values of x-italic primarily via hybridization with B s-italic,p-italic states. Evidence of increasing correlation effects with decreasing x-italic is found in the BIS spectra. This is suggested to be responsible for the observed magnetic property.
