متن کاملAngular correlations in breakup of three-body halo nuclei
We use the three-body model and the sudden approximation to compute angular correlations in high-energy fragmentation reactions of two-neutron halos on light targets. The contribution from one-neutron absorption by far dominates over that of neutron scattering. We use He (n1n1a) and Li (n1n1Li) as examples and study the dependence of the predictions of this model on different physical assumptio...
متن کاملCoulomb and nuclear breakup of three-body halo nuclei
– We investigate dissociation reactions of loosely bound and spatially extended three-body systems. We formulate a practical method for simultaneous treatment of long-range Coulomb and short-range nuclear interactions. We use He (n+n+α) and Li (n+n+Li) as examples and study the two-neutron separation cross sections as functions of target and beam energy. Individual Coulomb and nuclear as well a...
متن کاملA Realistic Solvable Model for the Coulomb Dissociation of Neutron Halo Nuclei
As a model of a neutron halo nucleus we consider a neutron bound to an inert core by a zero range force. We study the breakup of this simple nucleus in the Coulomb field of a target nucleus. In the post-form DWBA (or, in our simple model CWBA (“Coulomb Wave Born Approximation”)) an analytic solution for the T -matrix is known. We study limiting cases of this T -matrix. As it should be, we recov...
متن کاملProbing Halo and Molecular States in Light, Neutron-rich Nuclei
Until relatively recently cluster studies have been confined to the region encompassing the line of beta stability. As clustering is expected to manifest itself most strongly near thresholds, exotic structures might be expected to form in the more weakly bound systems found in the vicinity of the driplines. Perhaps the most striking example of this are the halo nuclei. In the present paper two ...
