Quadrupole collectivity of angular-momentum projected states of nucleons in the high-j intruder single-particle states

Ever since the pioneering work of Elliott (Elliott J P 1958 London Series A 245 128, 562), quadrupole collectivity in deformed nuclei has been economically described in terms of symmetry. Microscopic symmetry is not present in the deformed intrinsic states of n nucleons in the abnormal-parity single-particle states . However, such states do possess some -symmetry-like properties as shown in this work.
