New Detremination Method of Primordial Li Abundance

Astrophysics 2007-05-23 v1

Abstract

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