Description of the low-lying collective states of Zr based on the quadrupole-collective Bohr Hamiltonian
E. V. Mardyban, E. A. Kolganova, T. M. Shneidman +2
Experimental data on Zr indicate coexisting spherical and deformed structures with small mixing amplitudes. Several collective low-lying states and E2 and M1 transitions are…

D. A. Sazonov, E. A. Kolganova, T. M. Shneidman +3
Experimental data on Zr indicate coexisting spherical and deformed structures with small mixing amplitudes. We investigate the properties of the low-lying collective states…
Linking partial and quasi dynamical symmetries in rotational nuclei
C. Kremer, J. Beller, A. Leviatan +4
Background: Quasi dynamical symmetries (QDS) and partial dynamical symmetries (PDS) play an important role in the understanding of complex systems. Up to now these symmetry concept…
Proton-neutron symmetry in 92Zr, 94Mo with Skyrme interactions in a separable approximation
A. P. Severyukhin, N. N. Arsenyev, N. Pietralla
Starting from a Skyrme interaction we study the properties of the low-energy spectrum of quadrupole excitations in 90,92Zr, 92,94Mo. The coupling between one- and two-phonon terms…
