This work focuses in particular on octupole correlations, which cause the atomic nucleus to dynamically assume intrinsic reflection-asymmetric shapes such as a ¿pear¿ or ¿bananä shape. The most relevant fingerprints of these correlations are presented, along with the gamma-spectroscopy techniques that make it possible to identify them. The case of the nuclear species Barium-124 and Barium-125, populated in a fusion-evaporation reaction in which Nickel-64 projectiles impinged on a Nickel-64 target, is in particular addressed. It is shown how both barium isotopes do exhibit signatures of octupole correlations, i.e. low-lying negative-parity excited states and numerous electric-dipole transitions linking opposite-parity energy levels. It is also shown how these experimental results are consistent with theoretical expectations, as 56, the atomic number of Barium, corresponds to a single-particle configuration in which the proton Fermi level lies in the proximity of a pair of orbitals strongly coupled by the octupole interaction, i.e. h11\/2 and d5\/2.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838373584\"\u003e\u003ch3\u003eEvidence for Dynamical Intrinsic Reflection Asymmetry in Barium-124, 125\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838373584","offer_id":39499092263005,"sku":"9783838373584","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/bb105023-0856-4f91-a2b5-f3a887a8b665.jpg?v=1757655824","url":"https:\/\/shop.autorenwelt.de\/products\/octupole-signatures-in-moderately-neutron-deficient-barium-isotopes-von-paolo-mason","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
