Positron lifetimes in C60 and C70 fullerenes have been measured using Positron Lifetime technique. The analyzed lifetime spectra yields a single lifetime component in agreement with the earlier measurements. XRD measurements have also been used to characterize the fullerene samples. The C-60 and C-70 fullerenes have regular crystallographic face centered cubic structure with lattice constant a = 14.149 Angstrom and 14.903 Angstrom,respectively in good agreement with the literature data. The present positron results clearly support the conclusion that positrons do not Form positronium in fullerenes.
