C", "categories": [ "nucl-th" ], "abstract": "New reaction mechanisms occurring in heavy ion collisions at low energy (10- 30 MeV/A) are investigated within the Stochastic Mean Field model. We concentrate on the analysis of ternary breakup events, of dynamical origin, occurring in semi-central reactions, where the formation of excited systems in various conditions of shape and angular momentum is observed. We show how this fragmentation mode, which can be considered as a precursor of the neck emission observed at higher beam energies, emerges from the combined action of surface (neck) instabilities and angular momentum effects. Interesting perspectives are opening towards the investigation of this mechanism in neutron-rich (or exotic) systems, with the possibility to access information on the low-density behavior of the nuclear symmetry energy.", "revisions": [ { "version": "v1", "updated": "2014-07-03T09:21:25.000Z" } ], "analyses": { "subjects": [ "25.70.Mn", "24.60.Ky", "21.30.Fe", "25.70.Lm" ], "keywords": [ "heavy ion reactions", "exotic break-up modes", "low energy", "stochastic mean field model", "nuclear symmetry energy" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevC.90.054618", "journal": "Physical Review C", "year": 2014, "month": "Nov", "volume": 90, "number": 5, "pages": "054618" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1304718, "adsabs": "2014PhRvC..90e4618R" } } }
