| Abstract: | A decrease in the characteristic correlation time of light scattered by silicon particles in transformer oil and an increase
in their effective diffusion coefficient when the particle suspension in oil is exposed to a dc electric field were experimentally
shown. The current in the suspension did not exceed 100 nA and its temperature was unchanged. It was also shown that the shape
of the correlation function of light scattered by particles changes, i.e., a Gaussian factor appears in it. The dependences
of the exponential and Gaussian components on the electrode voltage are presented. |
