【 摘 要 】

Absolute cross sections are reported for double photoionization accompanied by loss of n C atoms (n 0, 2, 4, 6) of endohedral Xe@C+60molecular ions in the photon energy range 60 - 150 eV. The experimental data show clear evidence of confinement resonances arising from interference of outgoing 4d photoelectron waves.
