Abstract
We present a detailed reexamination of primordial big-bang nucleosynthesis (BBN), concentrating on the data for the main nuclear reactions leading to the production of 7Li, 3He, and D, and on the neutron half-life, relevant for 4He production. The new values for reaction rates and uncertainties are then used as input in a Monte Carlo analysis of big bang nucleosynthesis of light elements. This allows us to attach confidence levels to the predictions of the standard BBN model.
