Description of the asymmetric to symmetric fission transition in the neutron-deficient thorium isotopes: Role of the tensor force

Bernard, Remi; Pillet, N; Robledo, L M; Anguiano, M


In the present study, we have investigated the impact of the tensor force on fission paths, in particular the symmetric and asymmetric barriers in 230Th, 226Th, 222Th, and 216Th isotopes which display an asymmetric to symmetric fission transition. This analysis has been performed within the HFB approach with (Q20, Q30, Q40) as collective variable constraints, using the D1ST2a Gogny+tensor term interaction and comparing to the standard D1S Gogny interaction results. The effects from the tensor...[Show more]
