Abstract

The effect of β−-decay on the stability of metallofullerenes was investigated for three decay chains of155Sm-155Eu,161Gd-161Tb and177Yb-177Lu. For the former two cases, the metallofullerenes were found stable even after the β−-decay while in the case of177Yb, the metallofullerene became unstable after β−-decay. The present results point to the fact that metallofullerenes are stable against ordinary β−-decay unstable after β−-decay. The present results point to the fact that metallofullerenes are stable against ordinary β−-decay recoil energies, but they become unstable if the oxidation state of the metal atom is changed by nuclear transformation.
