N2 - We study the electronic structure of EuPtP, which exhibits two first-order valence transitions at T1 = 247 K and T2 = 201 K, using angle-resolved photoemission spectroscopy. Below T2, we observe an energy gap at the crossing point of the bulk Eu 4f and conduction bands. The shape of band dispersions is described by a hybridization-band picture based on the periodic Anderson model. Our results demonstrate the c-f hybridization effect in the low-temperature phase of EuPtP.
