• The collective rotation of a nuclear system having the quadrupole-quadrupole interaction is described by the dynamical nuclear field theory (DNFT). We use the one-body harmonic oscillator potential and restrict the discussion to the ΔN=0 transitions. Energy eigenvalues of the resulting SU_3 Hamiltonian are obtained by using the eigenstates of the cranked harmonic oscillator. Both the low and high spin states are studied by the perturbative DNFT, reproducing successfully the diagonalization results. In spite of the simple rotational spectrum, the nuclear shape is seriously influenced by the rotational disturbances. Similarities with our previous analyses of the pair rotation are pointed out. Especially, the SU_3 rotation in the odd mass system decouples with the particle motion just as the pair rotation does in the single-j limit.
