Title: Distortions in the cosmic background radiation and big-bang /sup 4/He nucleosynthesis

Abstract

The observed distortion of the cosmic background radiation is analyzed in the framework of information theory to derive a simple form of the photon occupation probability. Taking this distribution function as indicative of the Lagrange parameters which might characterize the era of nucleosynthesis during the big bang, and assuming equilibrium among the constituents present, we find that the primordial /sup 4/He abundance may be reduced by as much as 15% from the standard big-bang prediction.
