摘要

We determine primordial ⁷Li abundance independently of a previous method based on the measurment of the Spite plateau by using isotopic abundance ratios of ⁷Li/⁶Li in the interstellar media. The inferred best fit constraints on the primordial ⁷Li abundance is ⁷Li/H≃ 2.5 × 10^-10, and the conservative upper limit at the 95% confidence level turns out to be ⁷Li/H< 8 × 10^-10.
