Fecha de publicación: | nov-2007 | Editor: | Springer Nature | Citación: | The European Physical Journal - Special Topics 150(1): 137–138 (2007) | Resumen: | The aim of this work is to find out the origin of the anomalous resonance in Be-8 seen in the reactions through excited states in Be-9. We have populated the Be-9 excited states by beta-decay of Li-9. Energy and direction of the two alpha particles has been detected and the neutron spectra reconstructed. In our work we identified the "anomalous resonance" in Be-8 observed in several reaction studies as coming from the decay of the 2.43 and 2.78 MeV states in Be-9. This anomalous resonance appears when the two detected alpha particles are assumed to form a resonance in Be-8. We argued that the main decaying channels for these two levels in Be-9 do not involve Be-8. | Descripción: | 2 pages, 2 figures.-- PACS nrs.: 23.40.-s; 23.40.Hc; 27.20.+n. | Versión del editor: | http://dx.doi.org/10.1140/epjst/e2007-00287-3 | URI: | http://hdl.handle.net/10261/8862 | DOI: | 10.1140/epjst/e2007-00287-3 | ISSN: | 1951-6355 | E-ISSN: | 1951-6401 |
