Shape coexistence -- the concept for which an atomic nucleus may manifest different shapes depending on its excitation energy -- and shape evolution along isotopic chains are widespread phenomena throughout the nuclear chart, but we are still far from their comprehensive knowledge. In this context, the study of electric monopole (E0) transitions, connected to changes in the radial distribution of the charges in a nucleus, is fundamental.
Experimental evidence suggests that Sr and Zr isotopes around N=60 are ideal to study the properties related to the shape of atomic nuclei. For this reason, a dedicated beta-decay experiment was performed at the TRIUMF laboratories in Vancouver, Canada. A radioactive ion beam consisting mainly of 96Rb and 96Sr was produced and implanted at the center of GRIFFIN, a 4pi array of Compton-suppressed HPGe detectors equipped with a suite of ancillary detectors. Following the beta decay of the parent nuclei, the excited states of 96Zr and 96Sr were populated and studied.
In this contribution, the first results of the analysis concerning the low-energy states of 96Sr and 96Zr is presented, with a focus on their relevance in the shape coexistence framework.
