The quasi-particle bands with large contributions from $\\mathrm{U}~5f$ states were observed in the vicinity of $E_\\mathrm{F}$, suggesting that the $\\mathrm{U}~5f$ electrons of these compounds have an itinerant character. Their overall band structures were explained by the band-structure calculations treating all the $\\mathrm{U}~5f$ electrons as being itinerant.
