The neutron halo of 6He in a microscopic model
Abstract
The two--neutron separation energy of 6He has been reproduced for the first time in a realistic parameter--free microscopic multicluster model comprising the α +n+n and t+t clusterizations, with α cluster breathing excitations included. The contribution of the t+t channel is substantial. A very thick (0.85 fm) neutron halo has been found in full agreement with the results of the latest phenomenological analysis.
