Abstract

The yield curves for photoions from Ce@C 82 are measured by using synchrotron radiation in the photon energy range from 90 to 160 eV. Parent Ce@C 82 z+ and fragment ions C 60 z+ and C 70 z+ are observed in a mass spectrum (z=1 and 2). The yield curves for doubly charged ionic species exhibit broad resonance in the photon energy region of from 120 to 140 eV which is ascribed to the 4d→4f giant dipole resonance of the encapsulated Ce atom. The total photoabsorption cross section of Ce@C 82 was determined from partial photoionization cross sections for formation of the parent and fragment ions to be 5.3 -1.1 +1.8 and 19.6 -3.9 +6.5 Mb at photon energies of 110 and 130 eV, respectively.
