Solution of the Nuclear Shell Model by Symmetry-Dictated Truncation
M. W. Guidry, D. H. Feng, X. W. Pan +1
The dynamical symmetries of the Fermion Dynamical Symmetry Model are used as a principle of truncation for the spherical shell model. Utilizing the usual principle of energy-dictat…
Nuclear Shell Model Calculations with Fundamental Nucleon-Nucleon Interactions
X. W. Pan, T. T. S. Kuo, M. Vallieres +1
Some fundamental Nucleon-Nucleon interactions and their applications to finite nuclei are reviewed. Results for the few-body systems and from Shell-Model calculations are discussed…
Lifetime Measurements in 120Xe
J. C. Walpe, B. F. Davis, S. Naguleswaran +5
Lifetimes for the lowest three transitions in the nucleus Xe have been measured using the Recoil Distance Technique. Our data indicate that the lifetime for the $2_{1}^{+}…
Universality of Symmetry and Mixed-symmetry Collective Nuclear States
B. H. Smith, X. P. Pan, D. H. Feng +1
The global correlation in the observed variation with mass number of the and summed transition strengths is examined for rare earth nuclei. It is shown that a theory of c…
Single-Particle Nondegeneracy and SU(3) Fermion Dynamical Symmetry
Cheng-Li Wu, Da Hsuan Feng, Mike W. Guidry +2
It is shown that the SU(3) symmetry of the fermion dynamical symmetry model is essentially preserved even for highly nondegenerate spherical single-particle energies. The breaking…
A Revisit of SO(6) Dynamical Symmetry in Nuclear Structure
Xing-Wang Pan, Da Hsuan Feng
According to the analysis based on the fermion dynamical symmetry model, nuclei previously regarded as SO(6)-like (e.g. Xe and Pt) are shown to be more akin to the…
