Abstract

We discuss the primordial nucleosynthesis in lepton asymmetric Universe models. In order to better estimate the universal baryon-mass density parameter Ω_b, we try to remove the uncertainty from the theoretical prediction of primordial ⁷Li abundance. We propose a new method to determine the primordial ⁷Li by the use of isotopic abundance ratio ⁷Li/⁶Li in the interstellar medium which exhibits the minimum effects of the stellar processes.
