Fullerenes and fullerenols survival under irradiation

Fullerenes $\mathrm{C}_{2n}$, endometallofullerenes $\mathrm{Gd}$@$\mathrm{C}_{2n}$, $\mathrm{Gd}$@$\mathrm{C}_{82}$ and water-soluble $\mathrm{Gd}$@$\mathrm{C}_{2n}\mathrm{OH}_{38-40}$ derivatives were synthesized. These substances' survival dependences on the accumulated flux ($10^{16}$ – $10^{19}$ neutron/cm$^2$) of neutron irradiation over a wide spectrum of energies (from thermal to fast) in the WWR-M reactor zone (Petersburg Nuclear Physics Institute) have been examined.
