Abstract

The relativistic-Hartree-Bogoliubov formalism using density-dependent zero and finite range NN interactions, and separable pairing, is applied to the Kr isotopes (Z=36) and N=3464 isotopes, neutron-rich Sr(Z=38) and Zr(Z=40) nuclei with neutron numbers N=4870. A systematic search of triaxial ground state and the phenomena of unusual structural change and the coexistence of shape for Kr70100, and at N=58 in the Sr86108 and Zr88110 isotopes are done. A reasonable agreement is found with the available experimental data and with the macro-microscopic finite range droplet model. The findings are also in good agreement with the self-consistent Hartree-Fock-Bogoliubov calculations based on the interaction Gogny-D1S force, and with relativistic calculations.
