Abstract
The relativistic-Hartree-Bogoliubov formalism using density-dependent zero and finite range interactions, and separable pairing, is applied to the Kr isotopes () and isotopes, neutron-rich Sr() and Zr() nuclei with neutron numbers . A systematic search of triaxial ground state and the phenomena of unusual structural change and the coexistence of shape for , and at in the and 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.
