Primordial Lithium and Big Bang Nucleosynthesis
Ryan, Sean G.; Beers, T.C.; Olive, K.A.; Fields, B.D.; Norris, J.E. (2000)Recent determinations of the abundance of the light-element Li in very metal-poor stars show that its intrinsic dispersion is essentially zero and that the random error in the estimated mean Li abundance is negligible. ... -

The Spite Lithium Plateau: Ultrathin but Postprimordial
Ryan, Sean G.; Norris, J.E.; Beers, T.C. (1999)We have studied 23 very metal-poor field turnoff stars, specifically chosen to enable a precise measurement of the dispersion in the lithium abundance of the Spite Li plateau. -
