Description of He isotopes using the particle-particle random-phase approximation model
Abstract
The two-neutron RPA model has been used to describe helium isotopes with N (the neutron number) = 4, 6, 7, 8 in their ground and excited states. The properties of all these isotopes are given by a single system of equations so that their properties are interdependent. Since the ground states of He and He are still not well established, we have looked how the properties of He induce the properties of the other isotopes, energies and wave functions. Our results suggest an inversion of - shells in He. The corresponding ground states of He and He are slightly unbound and respectively and states while the and seen in experiments appear to be excited states. With this assumption on He, we get not only a nice picture of He but also a very good two-neutron separation energy in He.
