Low-lying resonance states in the Be-9 continuum
Artikel i vetenskaplig tidskrift, 2005

Excited states in Be-9 from 2 to 9 MeV are studied via beta delayed particle emission from Li-9. The broad overlapping particle unbound states are investigated using an extension of an experimental method developed for dealing with three-body decays of broad isolated levels. The results confirm the existence of a broad state at 5 MeV, with a width of 2 MeV. Angular correlations are used for firm spin determinations for this and other levels. (c) 2005 Elsevier B.V.
