Abstract
]]> For decades, single nucleon transfer reactions such as (d, p) have served as fundamental tools for studying the properties of nuclei throughout the periodic table. Their selectivity and ease of interpretation have made them some of the most heavily used reactions for the determination of quantum numbers, and for probing the wave functions of single–particle states in nuclei. With the advent of radioactive beams, interest in these simple transfer reactions has been renewed. I will review the utility of such reactions, and discuss some current applications in the context of the modern theoretical understanding of nuclear structure and in nuclear astrophysics. Finally, I will discuss two recent examples of studies of the (d, p) reaction carried out with radioactive beams to study the light nuclei 9Li and 7He, and present some of the challenges and opportunities that await in this new domain.Keywords: Nucleon transfer reactions; spectroscopic factors; radioactive beams.
Resumen
Reacciones de transferencia de un nucleon han funcionado por décadas como herramientas fundamentales para estudiar las propiedades nucleares. Por su selectividad y fácil interpretación dichas reacciones han sido las más usadas en la determinación de los números cuánticos y como prueba de las funciones de onda de los estados de partícula independiente. La disponibilidad de haces radioactivos ha causado un interes renovado en esas reacciones de transferencia. Se revisan y se discuten algunas aplicaciones recientes de esas reacciones en la estructura nuclear y la astrofísica nuclear. Finalmente, se estudia la reacción (d, p) llevada a cabo con haces radioactivos para investigar los nucleos ligeros 9Li y 7He, y se presentan algunos retos y oportunidades para el futuro.
Descriptores: Reacciones de transferencia de nucleones; factores espectroscopicos; haces radioactivos.
