The radioactive endohedral fullerenes 127Xe@C60, 127Xe@C70, 79Kr@C60, and 79Kr@C70, and their dimers, are detected using radiochemical and diochromatographic techniques in the final solution of samples in which Xe or Kr has penetrated into C60 or C70 by a nuclear reaction recoil process. Carrying out ab initio molecular dynamics simulations based on an all-electron mixed basis approach, we confirmed that the insertion of Xe and Kr atoms into C60 through six-membered rings is possible in a certain range of the kinetic energy: 130-200 eV for Xe and 80-150 eV for Kr.
