Abstract

Endohedral lanthanide metallofullerenes and their water-soluble biocompatible derivatives have been synthesized. The effect that fast-neutron irradiation has on the stability and nuclear physical properties of endohedral metallofullerenes that are used as magnetocontrast materials (46Sc, 140La, 141Nd, 153Sm, 152Eu, 154Eu, 153Sm, 160Tb, 169Yb, 170Tm (isomers I and III), and 177Lu) is studied. Our hypothesis, according to which carbon-shell relaxation is based on the fast nonradiative processes of an electron shake-off type, is confirmed.
