| The successful prediction of the measured abundances of deuterium and helium-4 relative to hydrogen by big-bang nucleosynthesis calculations is a major triumph of modern cosmology. There remain, however, significant discrepancies between observations and predictions for the absolute lithium-7 abundances and the lithium-6:lithium-7 isotope ratio. Possible resolutions of these "lithium problems" are that a larger reaction network must be taken into consideration, or that estimated cross sections in the existing network are grossly incorrect. Many aspects of the reaction network can be tested by using a D-T ignition shot at NIF. It is of particular interest that the full reaction network is automatically tested in this approach. In addition, the experimental prospects for debris collection from NIF shots will be discussed. |
