Quadrupole and hexadecapole correlations in rotating nuclei studied within the single-j shell model
- Institute of Physics, Warsaw University of Technology, ul. Koszykowa 75, PL--00-662 Warsaw (Poland)
The influence of quadrupole and hexadecapole residual interactions on rotational bands is investigated in a single-j shell model. An exact shell-model diagonalization of the quadrupole-plus-hexadecapole Hamiltonian demonstrates that the hexadecapole-hexadecapole interaction can sometimes produce a staggering of energy levels in the yrast sequence; however, long and regular {Delta}I=2 sequences are not obtained. The shell-model results are discussed in terms of the intrinsic deformations extracted by means of the self-consistent Hartree-Fock method. The angular momentum dependence of intrinsic quadrupole and hexadecapole moments Q{sub 2{mu}} and Q{sub 4{mu}} is investigated. {copyright} {ital 1997} {ital The American Physical Society}
