Yamashita, Marcelo Takeshi [UNESP]Frederico, T.Tomio, Lauro [UNESP]2014-05-272014-05-272007-03-26AIP Conference Proceedings, v. 884, p. 129-134.0094-243X1551-7616http://hdl.handle.net/11449/69579We report a renormalized zero-range interaction approach to estimate the size of generic weakly bound three-body systems where two particles are identical. We present results for the neutron-neutron root-mean-square distances of the halo nuclei 6He, 11Li, 14Be and 20C, where the systems are taken as two halo neutrons with an inert point-like core. We also report an approach to obtain the neutron-neutron correlation function in halo nuclei. In this case, our results suggest a review of the corresponding experimental data analysis. © 2007 American Institute of Physics.129-134engCorrelationFew-bodyHalo nucleiRoot-mean-square radiiTrabalho apresentado em evento10.1063/1.2710568WOS:000245812000016Acesso aberto2-s2.0-339473826042-s2.0-33947382604.pdf86212588459563483740639726545315
