An investigation of the tensor force effects on the spin-orbit splitting in spherical and very deformed nuclei

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

A contribution of the tensor force to the phenomenological spin-orbit (SO) potential in the single-particle Hamiltonian is studied for spherical and deformed rare-earth and actinide nuclei. It is found that the deformation dependence of the SO coupling constant, suggested by the second order tensor force contribution, enables to explain the observed single particle (s.p.) states in the second minimum of237Pu and239Pu using a SO strength weaker than usually applied. Consequences of the tensor contributions for the stability of theZ=114 superheavy nucleus are studied.
