“…Very recently two bands were attributed to 152 Pr in [46] and the energies of the transitions in the two bands are almost identical to those assigned to 151,153 Pr in the present work, hence one can assume that these are the same cascades. Some differences in these cascades exist however.…”

“…During the course of this work two publications have appeared, one of them very recently, which assigned bands to 151,153 Pr [8] and 152 Pr [46]. The parity-doublet bands assigned to 151,153 Pr in Ref.…”

“…12. It is not explained which transitions are used to make the mass assignment of A = 152 in [46]. One notes that if all transitions are used, or just the two lowest, one ends up with an average of the two masses 151 and 153, which is 152.…”

The neutron-rich praseodymium isotopes 151 Pr and 153 Pr have been studied by prompt γ-ray spectroscopy using 248 Cm and 252 Cf spontaneous-fission sources placed inside the EUROGAM-II and Gammasphere germanium arrays, respectively. Rotational bands, based on 3/2 − [541] states, with similar structures, have been assigned to these nuclei. These bands decay by intraband E2 transitions. Interband E1 transitions, reported in other works, were not observed. Delayed conversionelectron and γ-ray spectroscopy of an A = 151 nucleus has been performed at the Lohengrin mass spectrometer. A previously reported 35.1-keV isomer of 151 Pr has been determined to decay by an E1 transition and its half-life of 50(8) µs measured for the first time. Calculations performed using a reflection-symmetric quasi-particle-rotor model successfully reproduce the energies of the excited states of these nuclei and their decay patterns. The spin of the isomer has been assigned to be (1/2 + , 3/2 + ) from a comparison with the calculations. The long half life of this isomer and the lack of intraband E1 transitions show an absence of strong octupole correlations in the observed states of 151,153 Pr. This is explained in terms of increasing quadrupole deformation reducing the number of Nilsson orbitals close to the Fermi surface available to form octupole collectivity.
