By changing the diffuseness parameter of neutron density distribution in the droplet model for the projectile to obtain different ${\\delta}_{np}$, the relationship between ${\\delta}_{np}$ and the corresponding R(t/$^{3}$He) in semi-peripheral collisions is obtained. The calculated results show that R(t/$^{3}$He) has a strong linear correlation with ${\\delta}_{np}$ for neutron-rich $^{50}$Ca and $^{68}$Ni nuclei. It is suggested that R(t/$^{3}$He) could be regarded as a good experimental observable to extract ${\\delta}_{np}$ for neutron-rich nuclei because the yields of charged particles triton and $^{3}$He can be measured quite precisely.", "revisions": [ { "version": "v1", "updated": "2014-02-13T06:28:16.000Z" } ], "analyses": { "subjects": [ "21.10.Gv", "24.10.-i", "25.70.Mn" ], "keywords": [ "neutron skin thickness", "isospin-dependent quantum molecular dynamics", "droplet model", "neutron density distribution", "observable" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review C", "year": 2014, "month": "Jan", "volume": 89, "number": 1, "pages": "014613" }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1281271, "adsabs": "2014PhRvC..89a4613D" } } }
