Abstract (english)
Octupole deformations and related collective excitations are analyzed using the framework of nuclear density functional theory. Axially symmetric quadrupole-octupole constrained self-consistent mean- field (SCMF) cal- culations with a choice of universal energy density functional and a pairing interaction are performed for Xe, Ba, and Ce isotopes from proton-rich to neutron-rich regions, and neutron-rich Se, Kr, and Sr isotopes, in which enhanced octupole correlations are expected to occur. Low-energy positive- and negative-parity spectra and transition strengths are computed by solving the quadrupole- octupole collective Hamiltonian, with the inertia parameters and collective potential determined by the constrained SCMF calculations. Octupole-deformed equilibrium states are found in the potential energy surfaces of the Ba and Ce isotopes with N ≈ 56 and 88. The evolution of spectroscopic properties indicates enhanced octupole correlations in the regions corresponding toN≈Z≈56, Z≈88andZ≈56, andN≈56andZ≈34.Theaverageβ30 deformationparameterandits fluctuation exhibit signatures of octupole shape-phase transition around N = 56 and 88.
