  • Neutralization‐reionization mass spectrometry was used to show that for both neutral He@C60 and He@C, the noble gas atom is incorporated within the fullerene cavity. The C60H˙+ ions were generated by high‐energy collisions of C with quasi‐stationary 4He target atoms and cleaved in the mass spectrometer by loss of C2 or multiples thereof, as is usual for endohedral MC60 complexes.
