Abstract

Raman spectroscopy was used to analyze the effect of reactor neutron irradiation on the structure of polycrystalline C60. The samples were exposed to increasing reactor neutron doses including thermal, epithermal, and fast neutrons from ≈1014 to 1018n cm-2. The cumulative neutron doses were measured by Zr and Ni foil flux monitors. It was observed that the radiation had caused a structural damage to the crystals. Due to the damage, it was found that during irradiation at a dose of 1.32 · 1015 a surface decomposition starts, and at 7.56 · 10 16 the C60 started to behave like a black body.
