- Abstract
The condensed states of α-clusters or di-neutrons are studied by introducing a Monte Carlo technique for the description of the THSR (Tohsaki Horiuchi Schuck Röpke) wave function. The condensed state of five alpha particles is shown to be stable around the threshold energy even after taking into account the coupling effect between normal cluster states with 16O+α configurations. Next, the mixing of di-neutron components in 8He is studied. The ground state of 8He corresponds to the sub-closed-shell configuration of the spin-orbit favored orbits (p3/2) for the neutrons, and the shell-model-like configuration is considered to be dominant. However, 8He is a drip-line nucleus with a two-neutron separation energy of 2.1 MeV, and the di-neutron configuration, which is a characteristic feature of the weakly bound systems, mixes in the ground state. Finally, characteristic mechanism for the binding of clusters in neutron-rich nuclei (s2 bond) is discussed.
