Euler angles prescribing a body-fixed coordinate system are introduced by the use of the degeneracy of Hartree-Bogolyubov field in space orientation. To express such a degeneracy, a method of pair operations is applied. The Euler angles are quantized so as to recover the breaking of rotation symmetry. Collective rotational and intrinsic excitation modes are separated in a similar way to an RPA treatment. The importance of the non-canonical nature of a transformation to the body-fixed coordinate system is remarked. For simplicity, a single-j shell mode with pairing-plus-quadrupole force is adopted.
