We have calculated the electronic structure, photoelectron spectra, an
d magnetic moments for the UPdSn compound. The electronic structure an
d photoelectron spectra (x-ray photoemission spectroscopy) were calcul
ated using both itinerant as well as localized 5f states (using both a
n f2 and f3 configuration). By comparing our calculated results with e
xperimental data we argue that the localized f2 configuration is likel
y to be the most appropriate description for UPdSn.
