“…In the early 1990s three additional measurements of this spectrum were made: at TRI-UMF [12], at Yale [13,14], and at the University of Washington at Seattle (unpublished) [15]. The experiment reported here [16,17] is a continuation and improvement of the original Yale-UConn experiment [13,14].…”

“…Unfortunately, this task was not possible over the last two decades using conventional techniques and was only recently tackled using radioactive beams [9,10,11,12,13,14]. This cross section is needed to be measured at the most effective energy for helium burning (the Gamow window) of 300 keV.…”

“…I would also like to acknowledge discussions and encouragements from Professor Carlos Bertulani, Professor Gerhard Baur, and my collaborator Professor Thierry Delbar. Comparison of the spectra for beta-delayed alpha-particle emission of 16 N measured at Yale [9], TRIUMF [13] and Seattle [24]. [43].…”

“…While the two experiments are very different in their production of 16 N and detection method, and hence acquire different systematical error(s), they appear to be in agreement and quote similar S-factors, of similar accuracy and with good agreement. The R-Matrix analysis of the two experiments [9,23,14] In the Yale experiment [9,10], recoiling 16 N nuclei produced with a 9 MeV deuterium beams with the 15 N(d, p) 16 N reaction, were collected in a T i 15 N foil (with Au backing), tilted at 7…”

Some problems in nuclear astrophysics are discussed with emphasize on the ones central to the field which were not solved over the last two decades, including Helium Burning in massive stars (the 12 C(α, γ) 16 O reaction) and the 8 B Solar Neutrino Flux Problem (the 7 Be(p, γ) 8 B reaction). We demonstrate that a great deal of progress was achieved by measuring the time reverse process(es): the beta-delayed alpha-particle emission of 16 N and the Coulomb dissociation of 8 B, using Radioactive Beams (of 16 N and 8 B). In this way an amplification of the sought for cross section was achieved, allowing a measurement of the small cross section(s) of relevance for stellar (solar) processes. RESUMEN.Se discuten algunos problemas de astrofísica nuclear conénfasis en aquellos que son centrales de este campo que no han sido resueltos en lasúltimas dos décadas, incluyendose el consumo de Helio en las estrellas masivas (la reacción 12 C(α, γ) 16 O ) y el problema del flujo de Neutrinos Solares de 8 B (la reaccion 7 Be(p, γ) 8 B). Demostramos que se han hecho grandes progresos mediante la medida de los procesos invertidos en el tiempo: la emisión de partícula alfa retardada por beta de 16 N y la disociación coulombiana de 8 B, usando Haces Radioactivos (de 16 N y 8 B). En esta forma se logro una ampliación de la búsqueda de la sección, permitiendo la medida de seccion(es) pequeña(s) de relevancia para procesos estelares (solares).
