Abstract
Agreement between the predictions of standard big bang nucleosynthesis and the observed abundances of the light elements is achieved for a small range in values of the baryon to photon ratio, η near 3 × 10−10. At that value of η, the primordial deuterium abundance is about 7.5 × 10−5. ISM measurements of D indicate a present abundance 5 times smaller. Chemical evolution models are explored to achieve this degree of D destruction. Consistency with the 3He production in low mass stars and with the abundance of cosmo-chronometers is also discussed.
