The evolution of quadrupole and octupole collectivity in neutron-deficient Xe, Ba, Ce, and Nd nuclei near the "octupole magic" neutron number N = 56 is investigated within the mapped sdf -IBM framework. Microscopic input is obtained via quadrupole and octupole constrained Hartree-Fock-Bogoliubov calculations, based on the parametrization D1M of the Gogny energy density functional. Octupole-deformed mean-field ground states are predicted for Ba and Ce isotopes near N = 56. Excitation energies of positive-and negative-parity states as well as electric transition rates are computed with wave functions resulting from the diagonalization of the mapped IBM Hamiltonian. The parameters of the Hamiltonian are determined via the mapping of the mean-field potential energy surfaces onto the expectation value of the Hamiltonian in the condensate state of the s, d, and f bosons. Enhanced octupolarity is predicted for Xe, Ba, and Ce isotopes near N = 56. The shape/phase transition from octupole-deformed to strongly quadrupole-deformed near N = 60 is analyzed in detail.

Revisiting band structures in ¹¹⁸Xe nucleus via in-beam γ-ray spectroscopy*

The neutron deficient Xe nuclei with A ≈ 120 are predicted to have strong octupole correlation at low spins. Inthe present work, an attempt was made to improve upon the level scheme and also to look into the signatures ofoctupole correlation in 118Xe via high spin γ-ray spectroscopy. High spin states in 118Xe have been populated via93Nb(28Si,p2n)118Xe fusion-evaporation reaction at a beam energy of 115 MeV provided by the 15 UD pelletronaccelerator facility at IUAC, New Delhi. In the experiment, seven new γ-transitions have been found and are placedappropriately in the level scheme. Theoretical study using the triaxial projected shell model (TPSM) approachsuggests that the first bandcrossing is due to the alignment of two neutrons, and a parallel band tracking the yrastconfiguration is the γ-band built on the two-quasiparticle state. Enhanced E1 transition rates measured betweenopposite parity bands, involving νh11/2 and νd5/2 orbitals having ∆j = ∆l = 3, indicates the presence of octupolecorrelation in this nucleus
