Mixed Symmetry Nuclear Shell Model
J. P. Draayer, V. G. Gueorguiev, Feng Pan +1
A mixed-symmetry nuclear shell-model scheme for carrying out calculations in regimes where there is a competition between two or more modes is proposed. A one-dimensional toy model…
Algebraic Solutions of an Extended Pairing Model for Well-Deformed Nuclei
Feng Pan, V. G. Gueorguiev, J. P. Draayer
A Nilsson mean-field plus extended pairing interaction Hamiltonian with many-pair interaction terms is proposed. Eigenvalues of the extended pairing model are easy to obtain. Our i…
Study of Ti in a Mixed--Symmetry Basis
V. G. Gueorguiev, J. P. Draayer, W. E. Ormand +1
The structure of Ti is studied in an oblique-basis that includes spherical and SU(3) shell-model basis states. The results show that the oblique-basis concept is applicable,…
On the physical significance of q-deformation to isovector pairing interactions in nuclei
K. D. Sviratcheva, C. Bahri, A. I. Georgieva +1
The quantum deformation concept is applied to a study of isovector pairing correlations in nuclei of the mass 40<A<100 region. While the non-deformed (q -> 1) limit of the theory p…
Generalized q-Deformed Symplectic sp(4) Algebra for Multi-shell Applications
K. D. Sviratcheva, A. I. Georgieva, J. P. Draayer
A multi-shell generalization of a fermion representation of the q-deformed compact symplectic sp_q(4) algebra is introduced. An analytic form for the action of two or more generato…
Oblique-Basis Calculations for Ti
V. G. Gueorguiev, J. P. Draayer, W. E. Ormand +1
The spectrum and wave functions of Ti are studied in oblique-basis calculations using spherical and SU(3) shell-model states. Although the results for Ti are not as g…
Pseudo + quasi SU(3): Towards a shell-model description of heavy deformed nuclei
Jorge G. Hirsch, Carlos E. Vargas, Gabriela Popa +1
The pseudo-SU(3) model has been extensively used to study normal parity bands in even-even and odd-mass heavy deformed nuclei. The use of a realistic Hamiltonian that mixes many SU…
