• Systems of (j_1^2(proton), j_2^<±2>(neutron)) configurations are examined for the purpose of studying the role of neutron-proton correlation. Residual interactions of δ+QQ type are assumed. Protons and neutrons are strongly coupled by the attractive neutron-proton inter action (both short range and long range) which causes rotational features with the axial symmetry in two-proton and two-neutron systems. However, because the coupling of protons with neutron holes is weak, this leads the two-proton and two-neutron hole system to show no rotational property with the axial symmetry. In the former system, the ground K=0^+ band and also an excited K=1^+ band appear, provided that j_1 and j_2 are large and the QQ interaction is strong. Exact wave functions of the ground band members and K=1^+ band members are very similar to projected states from intrinsic wave functions given by the aligned coupling scheme.
