Two-body correlations in halo nuclei and effective interactions
Light nuclei with two particles (neutron or proton) or two holes outside a core have been studied in a two-particle RPA model with the Gogny and a zero range density dependent effective interactions. It has been shown that the model is able to consistently describe 6He, 14C, 12Be and 11Li. The case...

| Summary: | Light nuclei with two particles (neutron or proton) or two holes outside a core have been studied in a two-particle RPA model with the Gogny and a zero range density dependent effective interactions. It has been shown that the model is able to consistently describe
6He,
14C,
12Be and
11Li. The case of
12Be, described either as a
10Be-core plus two neutrons or as the core of
14Be, has been discussed in more details and a quasi boson expansion of the ground state wave function has been performed. To get consistent results in the two schemes one has suggested the same inversion of 2s and
1

shells in the n+
12Be average potential as known in the n+
10Be one. In the same model, a T=0 neutron-proton zero range effective interaction has been proposed to describe the 1
+, T=0 states in
14N and discussed in
10B. |
