photoabsorption by a Xe atom in a C 60 cage. The giant 4 d resonance in photoionization of
Xe is predicted to be redistributed into four components due to multipath interference of
photoelectron waves reflected by the cage. The measurements were made in the photon
energy range 60–150 eV by merging a beam of synchrotron radiation with a mass/charge
selected Xe@ C 60+ ion beam. The phenomenon was observed in the Xe@ C 58 3+ …
