[Phys. Rev. Lett. 97, 052701 (2006)]. We have also performed a comparison for the double ratio with experimental as well as different theoretical results of Boltzmann-Uehling-Uhlenbeck in 1997, Isospin-dependent Boltzmann-Uehling-Uhlenbeck in 2004, Boltzmann-Nordeim-Vlasov, and Improved QuantumMolecular Dynamics models. It is found that the double ratio predicts the softness of symmetry energy, which is a little underestimated in the single ratio. Furthermore, the study of the single ratio is extended for different kinds of fragments, while the double ratio is extended for different neutron-rich isotopes of Sn.", "revisions": [ { "version": "v1", "updated": "2011-11-17T17:32:34.000Z" } ], "analyses": { "subjects": [ "21.65.Ef", "25.70.Pq", "21.65.Cd", "25.70.-z" ], "keywords": [ "symmetry energy", "sub-saturation densities", "density dependence", "isospin-dependent quantum molecular dynamics model", "double ratio" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review C", "year": 2011, "month": "Oct", "volume": 84, "number": 4, "pages": "044620" }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "inspire": 944886, "adsabs": "2011PhRvC..84d4620K" } } }
