Description
Summary: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 ( 46 Sc, 140 La, 141 Nd, 153 Sm, 152 Eu, 154 Eu, 153 Sm, 160 Tb, 169 Yb, 170 Tm (isomers I and III), and 177 Lu) 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.
