Tensor force and deformation in even-even nuclei Co', G. Anguiano Millán, Marta Lallena Rojo, Antonio Miguel This work has been partially supported by the Junta de Andalucia (FQM387), the Spanish Ministerio de Economia y Competitividad (PID2019-104888GB-I00), and the European Regional Development Fund (ERDF). The variational principle is used to build a model which describes open shell nuclei with ground state deformations. Hartree-Fock equations are solved by using single particle wave functions whose radial parts depend on the projection of the angular momentum on the quantisation axis. Pairing effects are taken into account by solving Bardeen-Cooper-Schrieffer equations in each step of the minimization procedure. The Gogny D1S finite-range interaction and an extension of it that includes tensor terms are consistently used in both parts of our calculations. The model is applied to study a set of isotopes with 34 protons and of isotones with 34 neutrons. Total energies, density distributions, their radii, and single particle energies are analyzed and the results of our calculations are compared with the available experimental data. We focused our attention on the effects of the deformation and of the tensor force on these observables. Our model describes open shell nuclei from a peculiar perspective and opens the possibility of future theoretical developments. 2021-09-21T10:54:43Z 2021-09-21T10:54:43Z 2021-07-16 info:eu-repo/semantics/article Co', G., Anguiano, M., & Lallena, A.
