Nature of the ground state in α-cerium as studied by photoemission
Abstract
We have studied, through temperature-dependent resonant photoemission experiments, the changes in the 4f electronic states of the system Ce0.9Th0.1 produced by the first order γ-α valence transition. The results rule out the interpretation that the γ-α transition in cerium arises from the promotion of a 4f atomic-like state near the Fermi surface to the 5d, 6s conduction band. © 1982.
