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…
Basis Generator for M-Scheme SU(3) Shell Model Calculations
Vesselin G. Gueorguiev, Jerry P. Draayer
A FORTRAN code for generating the leading SU(3) irreducible representation (irrep) of N identical spin 1/2 fermions in a harmonic oscillator mean field is introduced. The basis sta…
Mixed-Mode Calculations in Nuclear Physics
V. G. Gueorguiev, J. P. Draayer
The one-dimensional harmonic oscillator in a box problem is used to introduce the concept of a mixed-mode shell-model scheme. The method combines low-lying ``pure mode'' states of…
Mixed-Mode Shell-Model Calculations
V. G. Gueorguiev, J. P. Draayer
A one-dimensional harmonic oscillator in a box is used to introduce the oblique-basis concept. The method is extended to the nuclear shell model by combining traditional spherical…
Excited bands in odd-mass rare-earth nuclei
C. E. Vargas, J. G. Hirsch, J. P. Draayer
Normal parity bands are studied in 157Gd, 163Dy and 169Tm using the pseudo SU(3) shell model. Energies and B(E2) transition strengths of states belonging to six low-lying rotationa…
SU(3) versus deformed Hartree-Fock
Calvin W. Johnson, Ionel Stetcu, J. P. Draayer
Deformation is fundamental to understanding nuclear structure. We compare two ways to efficiently realize deformation for many-fermion wavefunctions, the leading SU(3) irrep and th…
