Background: Several collective low-lying states are observed in $^{96}\mathrm{Zr}$ whose properties, which include excitation energies and $E2, E0$, $M1$ transition probabilities, indicate that some of them belong to the spherical state other deformed states. A consideration these data full framework geometrical Model with both intrinsic shape variables, $\ensuremath{\beta}$ $\ensuremath{\gamma}$, rotational degrees freedom is necessary for $^{96}\mathrm{Zr}$.Purpose: We investigate...
The properties of the collective low-lying states Zr isotopes which include excitation energies and $E2$ reduced transition probabilities indicate that some these are mainly spherical other deformed ones. We investigate $^{92-102}$Zr their evolution with increase number neutrons based on five-dimensional Geometrical Quadrupole Collective Model. quadrupole-collective Bohr Hamiltonian a potential having minima, is applied. relative depth two height width barrier, rigidity near both minima...
The angular momentum dependencies of parity splitting and electric dipole transitions in the alternating bands heavy nuclei have been analyzed. It is shown that these can be treated a universal manner with single critical parameter, which characterizes phase transition from octupole vibrations to stable deformation. Using simple but useful model axially-symmetric reflection-asymmetric mode, analytical expressions for transitional moment obtained. findings are good agreement experimental data...
The properties and description of the reflection-asymmetric mode in heavy nuclei are discussed. Two approaches based on collective octupole degree freedom mass asymmetry presented. Angular momentum dependence parity splitting, phase transition alternating rotational band, stabilization deformation with angular increase rigidity considered.
