“…It is useful to distinguish between different light sources employed in the photoabsorption experiments. Visible and infrared lasers, often pulsed and with high power, were extensively employed to study reactions of neutral endohedral fullerenes( [3] and references therein). Alternatively, high-energy photons from synchrotron radiation or free-electron laser sources have been employed.…”

A brief overview on the status of experimental investigations into photoionization and fragmentation of fullerenes and endohedral fullerenes by absorption of a single short-wavelength photon is presented. The focus of this paper is on the endohedral Xe@C 60 + molecular ion in which a xenon atom is centrally encapsulated inside a + C 60 fullerene cage. Confinement resonances that result from the interference of Xe photoelectron matter waves emerging from the + C 60 cavity were studied by exposing Xe@C 60 + ions to synchrotron radiation of 60 to 150eV energy which is the region of the well-known giant atomic Xe d 4 excitation resonance. Photoions Xe@C n q+ (with final charge states = q 2, 3, 4 of the product ions and numbers = n 60, 58, 56, 54 of carbon atoms left in the cage) were recorded as a function of photon energy and cross sections for the individual reaction channels were determined. In addition to previous work, new final channels ( = = q n 2; 60, 58 and = = q n 4; 58, 56) were observed, and thus, about 70% of the oscillator strength expected for the encapsulated Xe atom in the investigated energy range could be recovered. The present results establish the first and, so far, only conclusive experimental observation of confinement resonances in an endohedral fullerene. The data are in remarkable agreement with relativistic R-matrix calculations that accompanied the previous experimental work.

“…Effective methods to study such confined atoms are photoionization [3][4][5] and elastic scattering [6,7]. It has been rather difficult to perform such experiments due to the difficulty to produce sufficient amount of purified doped fullerenes in past decades, the situation becomes much better now [8][9][10][11][12]. Thus, the study of properties of atoms or small molecules encaged in fullerenes is turning into a promising area of new exciting investigations.…”

We report on elastic electron scattering cross sections from Ca and Mg confined by C60 and C20 using the optical potential method. We demonstrate the diffuse effect caused by a fullerene cage upon the elastic electron scattering process by employing a commonly used square-well potential and the recently ab initio calculated continuousness electrostatic potential. For Ca@C60, we found that the differential cross sections calculated by the continuousness electrostatic potential model are compatible with the square-well potential model while the square-well potential model tends to overestimate the integrated cross section than the continuousness electrostatic potential model. Results of electron collision from Mg@C20 have shown big discrepancies exist in both of the differential and integrated cross sections between two potentials, which implies that a new ab initio calculated electrostatic potential model should be preferred in future works. Moreover, the elastic scattering cross sections from Ca of the Ca±z@ have been calculated for the first time.

“…de fullerenes is associated with their response to electromagnetic radiation [7][8][9][10]. The references given in recent publications [11][12][13][14][15] provide an overview of experimental research in the field of photoionization and photofragmentation of fullerenes. Investigating many-particle systems such as molecules, clusters, and fullerenes by observing fine structure near atomic inner-shell photoabsorption edges is particularly elucidating.…”
