Abstract Microscopic structures of the proposed parity doublet bands in the odd-proton Z=61151Pm and Z=63153, 155Eu nuclei are examined using the quasiparticle phonon nuclear model Hamiltonian including the residual pairing and multipole-multipole interactions. Octupole correlations between intrinsic nonrotational states are studied to check the suggested assignments of parity doublet partners in these nuclei. We conclude significant octupole correlations between a pair ofK π = 1/2± doublets in each of these nuclei, with somewhat weaker correlations betweenK π = 3/2± bands in both the Eu isotopes. No octupole connection between the lowestK π = 5/2± bands is found; however, significant octupole collectivity, built on the low-lying 5/2− bands, is predicted in the higher-lying 5/2+ bands which contain the 5/2+ [402] fragmented strength.
