Recent Highlights of the DESPEC Experiment at FAIR Phase-0 — •Nicolas Hubbard for the DESPEC collaboration — Institut für Kernphysik, Technische Universitität Darmstadt, Germany — GSI Helmholtzzentrum für Schwerionenforschug, Darmstadt, Germany — Helmholtz Forschungsakademie Hessen für FAIR (HFHF) GSI Campus Darmstadt, Darmstadt, Germany
The DESPEC (DEcay SPECtroscopy) experiment is part of the NUSTAR pillar of FAIR and involves the measurement of decay properties of exotic radioisotopes far away from the valley of stability, in order to understand the nuclear force and the origin of the elements. This group report will report on the recent activities during 2022 of the DESPEC collaboration, including recent technical developments and preliminary results from two physics experiments performed at GSI in Darmstadt as part of the FAIR Phase-0 programme: The study of isomeric and beta decays of the N = 126 Nuclei 202Os and 203Ir, and the investigation of the β-strength crossing N = 126 and the formation of the 3rd r-process abundance peak via total absorption spectroscopy
