Abstract

We present the results of new theoretical work on surface Li7 and Li6 evolution in the oldest halo stars along with a new and refined analysis of the predicted primordial lithium abundance resulting from big-bang nucleosynthesis. This allows us to determine the constraints which can be imposed upon cosmology using primordial lithium and both standard big-bang and stellar-evolution models. This leads to a constraint on the baryon density today of 0.0044< bh2<0.025 (where the Hubble constant is 100h km sec-1 Mpc-1), and impose limitations on alternative nucleosynthesis scenarios.
