The collisional insertion of Cs+ ions into surface adsorbed C-60 molecules was studied by scattering Cs+ ion beams from a C-60 layer deposited on gold over the 35-220 eV impact energy range. Both Cs@C-60(+) and C-60(+) ions were ejected from the surface following the Cs+ impact but each species was characterized by different impact energy dependent yields and internal temperatures. Clear evidence for the endohedral nature of the complex is given. Both the scattering dynamics (at impact energies up to similar to100 eV) and the instant rise of the Cs@C-60(+) signal with the Cs+ beam onset clearly demonstrate that the insertion/ejection process is basically a single collision event. The outgoing Cs@C-60(+) and C-60(+) ions fragment during their flight time, after leaving the surface, via sequential emission of C-2 units down to Cs@C-50(+) and C-44(+), respectively. Relative impact energy dependent yields were measured for both parent species and for all fragments. The yield curves are kinetically shifted with respect to each other as expected. Comparing the impact energy dependent fragmentation patterns of C-60(+) and Cs@C-60(+) we conclude that the ejected Cs@C-60(+) ion is much hotter than the C-60(+) ion. The internal vibrational excitation for both species is reaching a maximal value around 90-110 eV impact energy and than gradually decreases with increase in impact energy. The integrated Cs@C-60(+) yield is strongly peaked at around 80+/-5 eV impact energy. At impact energies above 120 eV also a C-60(-) signal is observed but no Cs@C-60(-) could be detected.
