Broad states beyond the neutron drip line - Examples of H-5 and (4)n
Artikel i vetenskaplig tidskrift, 2004

Theoretical studies of broad states in the few-body systems beyond the neutron drip line have been performed. We introduce a theoretical model which allows to incorporate the initial structure of colliding nuclei, reaction mechanism, few-body effects and final-state interactions in studies of broad unbound states. The model is directly related to the sudden-removal approximation for high-energy knock-out or break-up reactions. We apply this model to qualitative studies of some general properties of broad few-body states including correlations for emitted fragments. The theoretical ideas are illustrated mainly using the example of 5 H. The prospect for observation of broad continuum structures corresponding to the tetraneutron 4 n is also discussed.
