The low-energy spectra and B(E2) electromagnetic transition strengths of Eu, Tb and Dy are described using the pseudo SU(3) model. Normal parity bands are built as linear combinations of SU(3) states, which are the direct product of SU(3) proton and neutron states with pseudo spin zero (for even number of nucleons) and pseudo spin 1/2 (for odd number of nucleons). Each of the many-particle stat...
متن کاملPseudo SU(3) shell model: Normal parity bands in odd-mass nuclei
A pseudo shell SU(3) model description of normal parity bands in 159Tb is presented. The Hamiltonian includes spherical Nilsson singleparticle energies, the quadrupole-quadrupole and pairing interactions, as well as three rotor terms. A systematic parametrization is introduced, accompanied by a detailed discussion of the effect each term in the Hamiltonian has on the energy spectrum. Yrast and ...
متن کاملEffects of Coriolis Perturbation on Normal-Parity Rotational Bands of Odd-Mass Nuclei
The puzzling behavior of the Ml transitions in a normal-parity band of 163Dy observed recently is studied in the framework of the particle· rotor model. Characteristic features of the Ml transitions as well as the energy spectrum are well reproduced by the present calculation. We have found that the Corio lis interaction gives rise to an appreciable amount of rotation alignment. A remarkable po...
متن کاملPseudo + Quasi Su(3): towards a Shell-model Description of Heavy Deformed Nuclei *
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(3) irreps has allowed for a successful description of energy spectra and electromagnetic transition strengths. While this model is powerful, there are situations in which the intruder states must be taken into accoun...
متن کاملDescription of deformed nuclei in the sdg boson model
We present a study of deformed nuclei in the framework of the sdg interacting boson model utilizing both numerical diagonalization and analytical 1=N expansion techniques. The focus is on description of high-spin states which have recently become computationally accessible through the use of computer algebra in the 1=N expansion formalism. A systematic study is made of high-spin states in rare-...
