摘要：

The frequency response of dielectric constant (epsilon') has been studied both in the pristine and irradiated samples in the frequency range 80 Hz to 100 kHz. The frequency dependence of dielectric response for pristine and irradiated samples reveals the presence of a low frequency dispersion and a loss peak that can be related to interfacial polarisation between neighbouring carbon rich clusters. Formation of such clusters due to heavy ion irradiation has been ascertained by FTIR studies. The frequency dependence of epsilon' in both pristine and irradiated samples has been found to obey a relation of the type epsilon' proportional to f(n-1), where n is a constant and f is the frequency.
