Di - neutron correlation in light neutron - rich nuclei
Using a three-body model with density-dependent contact interaction, we discuss the root mean square distance between the two valence neutrons in Li nuclues as a function of the center of mass of the neutrons relative to the core nucleus Li. We show that the mean distance takes a pronounced minimum around the surface of the nucleus, indicating a strong surface di-neutron correlation. We demonst...
متن کاملNew direct reaction: two-proton knockout from neutron-rich nuclei.
The reaction 9Be(28Mg,26Ne+gamma)X has been studied at 82 MeV/nucleon together with two similar cases, 30Mg and 34Si. Strong evidence that the reactions are direct is offered by the parallel-momentum distributions of the reaction residues and by the inclusive cross sections. The pattern of the partial cross sections for 28Mg suggests the presence of correlations. A preliminary theoretical discu...
متن کاملMolecular Structure with Exotic Clusters in light Neutron - rich Nuclei
The excited states of 12 Be, 14 Be and 15 B have been studied with a method of antisym-metrized molecular dynamics. In the predicted excited states we find novel molecule-like structures with very exotic clusters such as 6 He+ 8 He in 14 Be and 6 He+ 9 Li in 15 B. The origin of the 6 He cluster development in the very neutron-rich nuclei is understood by the new-type correlation among 4 neutron...
متن کاملInteraction cross sections for light neutron-rich nuclei
Interaction cross sections for nuclei with Z52 – 12 on a C target are calculated in the Glauber model with matter densities obtained from Skyrme Hartree-Fock and relativistic Dirac potentials. The shell-model orbital occupations and separation energies are taken from configuration-mixing calculations and experimental spectroscopic data. Halo effects are present in the most neutron-rich C and N ...
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 ...
