The 110Xe nuclei were produced via the 54Fe(58Ni,2n) fusion-evaporation reaction. The emitted 𝛾 rays were detected using the JUROGAM 3 𝛾-ray spectrometer, while the fusion-evaporation residues were separated with the MARA separator at the Accelerator Laboratory of the University of Jyväskylä, Finland. The experimental observation of the low-lying 3− and 5− states and inter-band E1 transitions between the ground-state band and the octupole band proves the importance of octupole correlations in this region. These new experimental data combined with theoretical calculations using the symmetry-conserving configuration-mixing method, based on a Gogny energy density functional, have been interpreted as an evidence of enhanced octupole correlations in neutron-deficient xenon isotopes.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal article1873-2445https://doi.org/10.1016/j.physletb.2023.138371https://www.sciencedirect.com/science/article/pii/S0370269323007050open access539.1Octupole deformations110XeN = Z = 56 regionFusion evaporation reactionsFísica nuclear2207 Física Atómica y Nuclear
