Decay studies in the A∼225 Po-Fr region from the DESPEC campaign at GSI in 2021

International audienceThe HISPEC-DESPEC collaboration aims at investigating the structure of exotic nuclei formed in fragmentation reactions with decay spectroscopymeasurements, as part of the FAIR Phase-0 campaign at GSI. This paper reportson first results of an experiment performed in spring 2021, with a focus on β-decaystudies in the Po-Fr nuclei in the 220 <A< 230 island of octupole deformationexploiting the DESPEC setup. Ion-beta correlations and fast-timing techniques arebeing employed, giving an insight into this difficult-to-reach region
