We conducted mass spectroscopy of molecules scattered on solid surfaces covered with ferrocene molecules in the presence of energetic C60 fullerene ions to investigate their encapsulation process. It is expected that Fe@C60 molecular ions exit a curved or tapered glass channel covered with ferrocene-terminated thiol self-assembled monolayer surfaces (SAMs) via multiple glancing collisions of C60 ions. We successfully measured the charge-state-specific mass spectra of exit ions using cylindrical glass and planar wedge channels. In the case of a planar wedge channel tilted 2° with respect to the C60-ion-beam axis, intensity enhancement and reduction were observed at masses around 776 u and below 720 u, respectively. Therefore, it is considered that particles with their mass around 776 u contain FeC60 molecules.
