Nucleosynthesis: what direct reactions can do for it?

Abstract

The reactions of relevance for stellar evolution are difficult to measure directly in the laboratory at the small astrophysical energies. In recent years indirect reaction methods have been developed and applied to extract low-energy astrophysical S-factors. These methods require a combination of new experimental techniques and theoretical efforts, which are the subject of this short review.Comment: 5 pages, 3 figures, Invited Talk at the Zakopane Conference on Nuclear Physics, Poland, 2012. arXiv admin note: substantial text overlap with arXiv:1110.253
