Abstract
The two-neutron separation energy of 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.
