Interplay between isoscalar and isovector correlations in neutron-rich nuclei
The interplay between isoscalar and isovector correlations in the 1- states in neutron-rich (N≠Z) even-even nuclei is studied, taking as examples of the nuclei, O14822 and O16824. The excitation modes explored are isovector dipole and isoscalar compression dipole modes. The self-consistent Hartree-Fock plus the random-phase approximation with the Skyrme interaction, SLy4, is solved in coordinate s
