Abstract
We report measurements of the de Haas-van Alphen effect in the heavy-electron metal Ce in the coherent state. Cyclotron masses of up to are observed and we deduce a many-body enhancement 20 times larger than in La. We conclude from the absence of any light electrons that the many-body renormalization leading to the coherent state influences all electrons, and not just those with primarily character.
