Description
The discrepancy between the primordial 7Li predicted abundance and the observed abundance in metal poor halo stars has been a longstanding problem. This problem may in fact be coupled with recent observational suggestions that there could be 2-3 orders of magnitude more 6Li than Big Bang Nucleosynthesis (BBN) calculations predict. We explore these issues by developing a more comprehensive nuclear reaction network. Some of the nuclear reactions incorporated have not previously been included in BBN calculations and few are well measured in the laboratory. We also discuss the effect of lepton captures on nuclei in BBN and present some calculations.
