Quasi-SU(3) truncation scheme for odd-even sd-shell nuclei
C. E. Vargas, J. G. Hirsch, J. P. Draayer
The quasi-SU(3) symmetry, as found in shell model calculations, refers to the dominance of the single particle plus quadrupole-quadrupole terms in the Hamiltonian used to describe…
Shell Model Description of Gd
G. Popa, J. P. Draayer, J. G. Hirsch
The pseudo-SU(3) model is used to describe the low-energy spectra as well as and transition strengths in Gd. The Hamiltonian includes spherical single-particle en…
Pseudo SU(3) shell model: Normal parity bands in odd-mass nuclei
C. E. Vargas, J. G. Hirsch, J. P. Draayer
A pseudo shell SU(3) model description of normal parity bands in 159-Tb is presented. The Hamiltonian includes spherical Nilsson single-particle energies, the quadrupole-quadrupole…
Quasi-SU(3) truncation scheme for even-even sd-shell nuclei
C. E. Vargas, J. G. Hirsch, J. P. Draayer
The Quasi-SU(3) symmetry was uncovered in full pf and sdg shell-model calculations for both even-even and odd-even nuclei. It manifests itself through a dominance of single-particl…
Band Crossing and Signature Splitting in Odd Mass fp Shell Nuclei
Victor Velazquez, Jorge G. Hirsch, Yang Sun
Structure of two sets of mirror nuclei: 47V - 47Cr and 49Cr - 49Mn, as well as 49V and 51Mn, is studied using the projected shell model. Their yrast spectra are described as an int…
Limitations of the number selfconsistent Random Phase Approximation
Alejandro Mariano, Jorge G. Hirsch
The Quasiparticle Random Phase Approximation equations are solved taking into account the Pauli Principle at the expectation value level, and allowing changes in the mean field occ…
Shell model description of normal parity bands in odd-mass heavy deformed nuclei
C. E. Vargas, J. G. Hirsch, T. Beuschel +1
The low-energy spectra and B(E2) electromagnetic transition strengths of 159Eu, 159Tb and 159Dy are described using the pseudo SU(3) model. Normal parity bands are built as linear…
