Abstract
Measurements of /spl epsi/" as a function of frequency and temperature have been undertaken in a preliminary investigation of the effects of neutron radiation on samples of an epoxy resin. Samples were produced from a diglycidel ether of bisphenol A resin. Transient discharging currents were also measured, and attempts were made to analyze the data using either the Hamon approximation or a Fourier transform technique. The preliminary data indicate that the DC transient is not governed by a t/sup -n/ dependence. Fourier analysis of these data to obtain low-frequency dielectric information indicates the presence of a loss peak. The increase of /spl epsi/" at lower frequencies observed in the loss analyzer data might be attributable to DC conductivity effects.<>
