Pseudo 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 single-particle energies, the quadrupole–quadrupole and pairing interactions, as well as three rotor terms. A systematic parametrization is introduced, accompanied by a det...

Summary:A pseudo shell SU(3) model description of normal parity bands in 159Tb is presented. The Hamiltonian includes spherical Nilsson single-particle 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 excited band wavefunctions are analyzed together with their B(E2) values.
