Examination of different strengths of octupole correlations in neutron-rich Pr and Pm isotopes

Popis výsledku v původním jazyce

Recent prompt gamma-ray spectroscopy studies of Pr-149,Pr-151 have revealed weak octupole correlations. These are manifested by the absence of strong intraband E1 transitions between bands of opposite parities. On the other hand, in their isotones Pm-151,Pm-153, which have only two additional protons, the E1 transition rates are several orders of magnitude stronger, indicating enhanced octupole correlations. The quasiparticle phonon model combined with the particle-rotor model, which allows octupole correlations and Coriolis mixing to be taken into account, has been applied to calculate the E1 transition rates between low-lying states of the nuclei Pr-149,Pr-151 and Pm-151,Pm-153. The dependence of the E1 rates on the magnitude of the quadrupole deformation, the magnitude and sign of the hexadecapole deformation parameter, the Coriolis and recoil attenuation parameters, the energies of the vibrational bandheads, and the parameters of the Nilsson Hamiltonian have been thoroughly investi
