Quasi-free scattering of light neutron defficient nuclei

Resumo

This dissertation studies nuclear reactions, performed with relativistic radioactive beams in the experimental laboratory R3B-LAND located at GSI, in Darmstadt. The manuscript presents single-nucleon removal, Quasi-Free Scattering and fragmentation reactions focusing on asymmetric isospin matter, in particular, neutron-deficient nuclei, such as oxygen (A=13-22), and nitrogen (A=12-16). We could infer reaction mechanism included in the single-removal channels via cross-checking with QFS and other measurable channels that produce the same final fragments. It has been also obtained information on the structure of the exotic nuclei thanks to the comparison with theoretical calculations. The estimated reduction factor (Rs), which takes into account how well the model reproduce the experimental measurements, reflects a slight dependence on the asymmetry and confirming previous results. In addition, momentum distributions of the final fragments, which are a useful tool to exploit single-particle information of the nucleons, afford to understand the behaviour of the studied channels. La presente tesis estudia reacciones nucleares centrándose en materia de isoespín asimétrica, en particular en núcleos deficitarios en neutrones, realizado en R3B-LAND, (GSI Darmsdadt). Se ha podido inferir el mecanismo de reacción, se ha obtenido información sobre las estructura de los núcleos exóticos gracias a las comparaciones de secciones eficaces y distribuciones de momentos con las predicciones teóricas.
