Abstract :
Samples of Ar1C60 (both powder and films) were produced by hot isostatically pressing C60 in an atmosphere of Ar at 170 MPa. The prepared samples of Ar1C60 were irradiated with neutrons in a high flux nuclear reactor for a period of 4 h. In each case, the material was exposed at 300 K to a thermal neutron flux of 5 × 1013 neutrons cm−2s−1. The measured activity of the 41Ar showed that there was no evidence of escape of the activated species from the lattice as a result of the neutron irradiation. IR spectroscopy, X-ray diffraction with Rietveld analysis, and transmission electron microscopy in conjunction with energy dispersive X-ray spectroscopy showed that Ar in general was not lost from the lattice as a result of being exposed to the harsh nuclear reactor conditions associated with the neutron irradiation.
