Abstract:

Nucleosynthesis in the universe with isothermal density fluctuations is investigated. It is shown that neutrons in low-density regions diffuse back to high-density regions. Thus the abundances of light elements contradict with Ω_B=1 if the scale of density fluctuations is as small as 10⁴ cm at T=1 MeV.
