Crowns of neutrons: reactions and decays to penetrate the halos of Be-14 and He-8


"Light, neutron-rich isotopes are some of the most exotic and fascinating nuclei to study with radioactive ion beams. The vicinity of the neutron dripline and the fundamental properties of the nucleon-nucleon interaction give rise, in this isotopes, to a wealth of concurrent phenomena which constitute a considerable experimental and theoretical challenge, such as nuclear halos, nuclear clustering, coupling to the continuum, and shell structure evolution. Because of this rich variety, they constitute also privileged systems to study in depth the fundamental properties of the nucleon-nucleon interaction, such as the role played by three-body forces.
This project focuses on gathering new fundamental data to unveil some not yet understood aspects of the structure of two key isotopes in the region, Be-14 and He-8. Be-14 lies on the dripline and He-8 is the only known isotope to possess a 4-neutron halo. Specific spectroscopic aspects which characterize their structure will be studied experiments with low-intensity radioactive beams by studying beta-delayed particle emission via the MAYA active target detector and by implanting the beams on highly segmented silicon detector.
Furthermore, to considerably improve the current detecting potential of active target detectors, the project will also involved the research and development stage of the latest-generation active target development, ACTAR. The specific contribution of this project will be the design and development of ancillary Si-CsI detectors to be coupled to this new state-of-the-art gaseous target."
