In 4f compounds, there is a two-peaked structure associated with 4f photoemission spectroscopy, while most 5f compounds yield a single broad triangular-shaped 5f intensity. Evidence is presented from measurements on ternary alloys that show that at least part of the extra-5f intensity is due to the hitherto missing main peak (or d-screened f-hole peak) just as in the 4f systems. The remaining intensity is consistent with a band structure DOS. (The compounds used were URh/sub 3/B/sub x/, UPd/sub x/Rh/sub 3-x/, ThBe/sub 13/, UIr/sub 3/, and UBe/sub 13/.) (DLC)
