Exactly Solvable Pairing Models
J. P. Draayer, V. G. Gueorguiev, K. D. Sviratcheva +3
Some results for two distinct but complementary exactly solvable algebraic models for pairing in atomic nuclei are presented: 1) binding energy predictions for isotopic chains of n…
Description of heavy deformed nuclei within the pseudo-SU(3) shell model
Gabriela Popa, Ana Georgieva
We present a review of the pseudo-SU(3) shell model and its application to heavy deformed nuclei. The model have been applied to describe the low energy spectra, B(E2) and B(M1) va…
Simultaneous Description of Even-Even, Odd-Mass and Odd-Odd Nuclear Spectra
H. G. Ganev, A. I. Georgieva
The orthosymplectic extension of the Interacting Vector Boson Model (IVBM) is used for the simultaneous description of the spectra of different families of neighboring heavy nuclei…
New Description of the Doublet Bands in Doubly Odd Nuclei
H. G. Ganev, A. I. Georgieva, S. Brant +1
The experimentally observed doublet bands in some odd-odd nuclei are analyzed within the orthosymplectic extension of the Interacting Vector Boson Model (IVBM). A new, pur…
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…
