Description

Angular resolved photoemission on an in situ cleaved USb single crystal was undertaken using synchrotron radiation from 20 to 130 eV. A good correspondence between the observed and calculated peaks is obtained. Very strong enhancement of uranium 5f photoemission is observed for hν = 98 eV. We interpret this effect as an interference between the two excitation channels 5f + hν → epsilonsub(g) and 5d + hν → 5f giving rise to a Fano-type profile for the intensity of the U-5f line.
