Tensor interaction in mean-field and density functional theory approaches to nuclear structure / H. Sagawa, G. Colo'. - In: PROGRESS IN PARTICLE AND NUCLEAR PHYSICS. - ISSN 0146-6410. - 76(2014), pp. 76-115. [10.1016/j.ppnp.2014.01.006]
Abstract:
The importance of the tensor force for nuclear structure has been
recognized long ago. Recently, the interest for this topic has been
revived by the study of the evolution of nuclear properties far from the
stability line. However, in the context of the effective theories that
describe medium-heavy nuclei, the role of the tensor force is still
debated. This review focuses on ground-state properties like masses and
deformation, on single-particle states, and on excited vibrational and
rotational modes. The goal is to assess which properties, if any, can
bring clear signatures of the tensor force within the mean-field or
density functional theory framework. It will be concluded that, while
evidences for a clear neutron proton tensor force exist despite
quantitative uncertainties, the role of the tensor force among equal
particles is less well established.
