Abstract
Accurate nuclear reaction rates are needed for primordial nucleosynthesis and hydrostatic burning in stars. The relevant reactions are extremely difficult to measure directly in the laboratory at the small astrophysical energies. In recent years direct reactions have been developed and applied to extract lowenergy astrophysical Sfactors. These methods require a combination of new experimental techniques and theoretical efforts, which are the subject of this presentation.
Keywords: Direct reactions; reactions induced by unstable nuclei; nuclear astrophysics.
Resumen
Tasas precisas de reacciones nucleares son importantes para la síntesis nuclear primordial y la quema hidroestática en estrellas. Las reacciones relevantes son extremadamente difíciles para medir en el laboratorio para las energías de interés para la astrofísica. Recientemente se han desarrollado reacciones directas para determinar factores S astrofísicas a bajas energías. Estos métodos requieren una combinación de técnicas experimentales nuevas y cálculos teóricos, que se discuten a continuación en esta contribución.
Descriptores: Reacciones directas; reacciones inducidas por núcleos inestables; astrofísica nuclear.
