From transmission and reflection measurements on glow discharge prepared a-Si:Hx(x=0.09-0.19) films we obtain the imaginary part of the dielectric constant, e2 in the range 1.4 to 3.8 eV. We compare this data with the prediction of a model first introduced by Tauc for optical transitions, with momen
