[en] Quantal form of the dynamical nuclear field theory is used for the description of the collective rotation of a nuclear system with the SU₃ Hamiltonian. Low spin states for an axially symmetric configuration with maximum alignment and K = 0 are treated. A residual part of the QQ force, which restores the rotational invariance of the intrinsic Hamiltonian, is employed together with the Coriolis coupling. The effective particle angular momentum is equal to that of the rotor up to second order. The effective Hamiltonian coincides with the exact SU₃ energy. The E2-matrix elements within the K = 0 band agree with the exact values given by Bohr and Mottelson. (author)
