Mass‐selected beams of endohedral fullerene ions, of atomic ions ( 3, 4), and of empty fullerene‐cage ions were employed to study photoionization of fullerene‐encapsulated and free cerium atoms. The Ce 4d inner‐shell contributions to single and double ionization of the endohedral fullerene have been extracted from the data and compared with expectations based on theory and the experiments with atomic Ce ions. Dramatic reduction and redistribution of the ionization contributions to Ce 4d photoabsorption is observed. More than half of the Ce 4d oscillator strength is apparently diverted to additional decay channels of the complex.
