Low energy 0+ excitations in 158Gd
Jorge G. Hirsch, Gabriela Popa, Shelly R. Lesher +3
High precision (p,t) studies of the deformed nucleus 158Gd allowed the observation of 13 excited 0+ states below an excitation energy of 3.1 MeV. This high density of low energy st…
Extended Pairing Model for Heavy Nuclei
V. G. Gueorguiev, Feng Pan, J. P. Draayer
We study binding energies in three isotopic chains (Sn, Yb, and Pb) using the extended pairing model with Nilsson single-particle energies. The…
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…
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…
Mixed-Symmetry Shell-Model Calculations
V. G. Gueorguiev, J. P. Draayer
The one-dimensional harmonic oscillator in a box problem is used to introduce the concept of an oblique-basis shell-model theory. The method is applied to nuclei by combining tradi…
