New Detremination Method of Primordial Li Abundance
Abstract
We discuss the primordial nucleosynthesis in lepton asymmetric Universe models. In order to better estimate the universal baryon-mass density parameter Ωb, 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.
