Abstract
High-resolution angle-resolved photoemission spectroscopy at low tempe rature has been performed on the low-carrier Kondo material CeP. It wa s found that the p-f bonding state with a dominant 4f character exhibi ts a finite-energy dispersion of about 40 meV along the TX direction i n the Brillouin zone. This implies that 4f electrons in CeP form a nar row band owing to the strong anisotropic p-f and d-f mixing.
