Title: Indirect Methods For Nuclear Astrophysics With Radioactive Nuclear Beams

Abstract

For a good understanding of nucleosynthesis and energy production in stars through reliable modeling, we need nuclear data. To obtain them is the goal of nuclear physics for astrophysics, using direct and indirect measurements. In this lecture indirect methods for nuclear astrophysics are reviewed. In particular, methods applied to extract reaction rates for H-burning in stars are treated. The Coulomb dissociation is first briefly touched, for completeness. Then I go to one-nucleon transfer reactions (the ANC method), breakup reactions at intermediate energies and decay spectroscopy (beta-decay and beta-delayed proton-decay). They involve the use of radioactive nuclear beams. I chose for exemplification different experiments of our Texas A and M group, each involving a different method. The experiments were done at large energies to extract selected nuclear structure information. That is in turn used to evaluate the cross sections at low energies and the reaction rates for nuclear astrophysics. I will show the specificities of each method, their complementarities and redundancies, insisting on their peculiarities when used with radioactive beams.
