Photoionization of the endohedral fullerene ions
The first experimental results on photoionization of mass-selected endohedral Sc3N@C + 80 and Ce@C + 82 fullerene ions are reported. The merged-beams technique was employed to measure photo-ion yield spectra as well as absolute cross sections. Comparing the results of endohedral fullerenes with those obtained using ”empty” C+80 and C + 82 ions provides insight into the mutual influence of the f...
متن کاملInner-Shell Ionization and Fragmentation of Isolated Endohedral Fullerene Ions by XUV Radiation
The photon–ion merged-beams technique for photoabsorption studies of ionized nanoparticles with synchrotron radiation is introduced. As an example, recent results from photoionization and photofragmentation of the endohedral fullerene ions Lu3N@C 80, Lu3N@C 2+ 80 , and Lu3N@C 3+ 80 are briefly discussed, highlighting the sensitivity and versatility of the experimental technique.
متن کاملFullerene-Encapsulated Atoms in the Light of Synchrotron Radiation
Mass-selected beams of endohedral fullerene Ce@C82 ions, of atomic Ce q+ ions (q=2,3,4), and of empty fullerene-cage C82 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 Ce@C82 fullerene have been extracted from the data and compared with expectations based on theory...
متن کاملSignificant redistribution of Ce 4d oscillator strength observed in photoionization of endohedral Ce@C82+ ions.
Mass-selected beams of atomic Ceq+ ions (q = 2, 3, 4), of C82+ and of endohedral Ce@C82+ ions were employed to study photoionization of free and encaged cerium atoms. The Ce 4d inner-shell contributions to single and double ionization of the endohedral Ce@C82+ fullerene have been extracted from the data and compared with expectations based on theory and the experiments with atomic Ce ions. Dram...
متن کاملTwo-electron photoionization of endohedral atoms
Using He@C60 as an example, we demonstrate that static potential of the fullerene core essentially alters the cross section of the two-electron ionization differential in one-electron energy dσ++(ω)/dε. We found that at high photon energy prominent oscillations appear in it due to reflection of the second, slow electron wave on the C60 shell, which ”dies out” at relatively high ε values, of abo...
