High energy collisions of Kr@C 60 +. with stationary helium atoms provide additional evidence that - as demonstrated earlier (Saunders, Jiménez-Vázquez, Cross, Mroczkowski, Gross, Giblin and Poreda) - a krypton atom penetrates the carbon network of C 60-fullerenes under thermal conditions (15 atm, 600°C, 2h). In the collision experiments, signals are also observed that can best be explained in terms of a HeKr@C 60 +. compound.
