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 10 4 cm at T =1 MeV.Keywords
