An exact shell-model diagonalization of quadrupole-plus-hexadecapole interaction can sometimes produce a staggering of energy levels in the yrast bands.15 pages, 9 Postscript figures, REVTEX, to be published in PRCNuclear TheoryQuadrupole and Hexadecapole Correlations in Rotating Nuclei Studied within the Single-j Shell Modeltext
