The octupole collective Hamiltonian. Does it follow the example of the quadrupole case?
S. G. Rohozinski, L. Prochniak
A general form of the octupole collective Hamiltonian is introduced and analyzed based on fundamental tensors in the seven-dimensional tensor space. Possible definitions of intrins…
Gaussian Overlap Approxomation for the quadrupole collective states
Stanisław G. Rohoziński
The Generator Coordinate Method (GCM) in the Gaussian Overlap Approximation (GOA) is applied to a description of the nuclear quadrupole collective states. The full five-dimensional…
Signatures of chirality in the core-particle-hole systems
S. G. Rohozinski, L. Prochniak, Ch. Droste +1
An odd-odd nucleus is treated as the core-particle-hole system. The core is described by the Bohr Hamiltonian. Different collective potentials of the core are investigated. The odd…
Quadrupole collective states within the Bohr collective Hamiltonian
L. Prochniak, S. G. Rohozinski
The article reviews the general version of the Bohr collective model for the description of quadrupole collective states, including a detailed study the model's kinematics. The gen…
Self-consistent symmetries in the proton-neutron Hartree-Fock-Bogoliubov approach
S. G. Rohozinski, J. Dobaczewski, W. Nazarewicz
Symmetry properties of densities and mean fields appearing in the nuclear Density Functional Theory with pairing are studied. We consider energy functionals that depend only on loc…
Local Density Approximation for proton-neutron pairing correlations. I. Formalism
E. Perlinska, S. G. Rohozinski, J. Dobaczewski +1
In the present study we generalize the self-consistent Hartree-Fock-Bogoliubov (HFB) theory formulated in the coordinate space to the case which incorporates an arbitrary mixing be…
Kerman-Klein-Donau-Frauendorf model for odd-odd nuclei: formal theory
A. Klein, P. Protopapas, S. G. Rohozinski +1
The Kerman-Klein-Donau-Frauendorf (KKDF) model is a linearized version of the Kerman-Klein (equations of motion) formulation of the nuclear many-body problem. In practice, it is a…
Collective Quadrupole Excitations in Transitional Nuclei
K. Pomorski, L. Prochniak, K. Zajac +2
The generalized Bohr Hamiltonian was used to describe the low-lying collective excitations in even-even isotopes of Ru, Pd, Te, Ba and Nd. The Strutinsky collective potential and c…
Point symmetries in the Hartree-Fock approach: Symmetry-breaking schemes
J. Dobaczewski, J. Dudek, S. G. Rohozinski +1
We analyze breaking of symmetries that belong to the double point group D2h(TD) (three mutually perpendicular symmetry axes of the second order, inversion, and time reversal). Subg…
Point symmetries in the Hartree-Fock approach: Densities, shapes and currents
J. Dobaczewski, J. Dudek, S. G. Rohozinski +1
Three mutually perpendicular symmetry axes of the second order, inversion, and time reversal can be used to construct a double point group denoted by D2h(TD). Properties of this gr…
The low-lying quadrupole collective excitations of Ru and Pd isotopes
K. Zajac, L. Prochniak, K. Pomorski +2
Quadrupole excitations of even-even Ru and Pd isotopes are described within microscopic approach based on the general collective Bohr model which includes the effect of coupling wi…
Collective quadrupole excitations in the 50<Z,N<82 nuclei with the generalized Bohr Hamiltonian
L. Prochniak, K. Zajac, K. Pomorski +2
The generalized Bohr Hamiltonian is applied to a description of low-lying collective excitations in even-even isotopes of Te, Xe, Ba, Ce, Nd and Sm. The collective potential and in…
