Abstract

The ground state properties of La isotopes are investigated with the reflection asymmetric relativistic mean field (RAS-RMF) model. The calculation results of binding energies and the quadrupole moments are in good agreements with the experiment. The calculation results indicate the change of the quadrupole deformation with the nuclear mass number. The “kink” on the isotope shifts is observed at A = 139 where the neutron number is the magic number N = 82. It is also found that the octupole deformations may exist in the La isotopes with mass number A ∼ 145–155.
