Title: | Shape evolution in Kr, Zr and Sr isotopic chains in covariant density functional theory. | Authors: | Abusara, H. Ahmad, Shakeb |
Keywords: | Shape evolution in Kr;Shape evolution in Zr;Shape evolution in Sr;Isotope shift | Issue Date: | 2017 | Abstract: | The relativistic-Hartree-Bogoliubov formalism using density-dependent zero and finite range N-N interactions, and separable pairing, is applied to the Kr isotopes (Z = 36) and N = 34 - 64 isotopes, neutron-rich Sr(Z=38) and Zr(Z=40) nuclei with neutron numbers N=48-70. A systematic search of triaxial ground state and the phenomena of unusual structural change and the coexistence of shape for 70−100Kr, and at N=58 in the 86−108Sr and 88−110Zr 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 | URI: | http://hdl.handle.net/20.500.11889/8110 |
