Abstract
We have used the random phase model for the electronic wave functions to calculate the
imaginary part of the dielectric function 82 (m) and the magnitude of the third harmonic
generation, 11'3(OJ ~ using a model structure of a-Si containing 1728 atoms. We show that this
simple calculation gives reasonable results for e(e) and furthermore the behaviour of .l. «(l). is
similar to more detailed theoretical calculations
