Abstract

We investigate nucleosynthesis in the universe with isothermal baryon density fluctuations taking into account nucleon diffusion during the nucleosynthesis. We find Ω _B = 1 universe is marginally consistent with the light element abundances (D, ³ He, ⁴ He, ⁷ Li) if the density contrast, R is very high, ≳300 and the other parameters are tuned.
