Transition probabilities in the U(6) limit of the Symplectic Interacting Vector Boson Model
H. G. Ganev, A. I. Georgieva
The tensor properties of the algebra generators and the basis are determined in respect to the reduction chain $Sp(12,R) \supset U(6)% \supset U(3)\otimes U(2)\supset O(3)\otimes (…
Microscopic Description of Isospin Mixing Pairing Correlations in the Framework of an Algebraic Sp(4) Model
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
We explore isospin mixing beyond that due to the Coulomb interaction in the framework of an exactly solvable microscopic sp(4) algebraic approach. Specifically, we focus on the iso…
Isospin symmetry breaking in an algebraic pairing Sp(4) model
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
An exactly solvable sp(4) algebraic approach extends beyond the traditional isospin conserving nuclear interaction to bring forward effects of isospin symmetry breaking and isospin…
Dynamical symmetry of isobaric analog 0+ states in medium mass nuclei
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
An algebraic sp(4) shell model is introduced to achieve a deeper understanding and interpretation of the properties of pairing-governed 0+ states in medium mass atomic nuclei. The…
Physical Significance of q Deformation and Many-Body Interactions in Nuclei
K. D. Sviratcheva, C. Bahri, A. I. Georgieva +1
The quantum deformation concept is applied to a study of pairing correlations in nuclei with mass 40<A<100. While the nondeformed limit of the theory provides a reasonable overall…
Analytic Formulae for the Matrix Elements of the Transition Operators in the Symplectic Extension of the Interacting Vector Boson Model
H. G. Ganev, A. I. Georgieva, V. P. Garistov
The tensor properties of all the generators of Sp(12,R) - the group of dynamical symmetry of the Interacting Vector Boson Model (IVBM), are given with respect to the reduction chai…
