Reaction studies around the Ca isotopic chain in inverse kinematics with the R3B setup — •Christian Sürder for the R3B collaboration — Institut für Kernphysik, TU Darmstadt, Germany

In Feb. 2020 an experiment to study isotopes around the Ca isotopic chain, reaching from the proton-rich to the neutron-rich side, was performed with the versatile R3B setup at GSI, Darmstadt, Germany. The isotopes were produced through fragmentation of a primary beam of ⁸⁶Kr at a beam energy of 580MeV/A on a ⁹Be target. The secondary cocktail beam included isotopes of Cr, V, Ti, Sc, Ca, K, Ar and Cl. This experiment, part of the R3B Phase 0 program at FAIR, allowed for exclusive studies in inverse kinematics, employing reactions like (p2p), (p2pn), etc. The knocked out particles were detected with CALIFA, a CsI detector with high granularity, situated around the target area. The talk focuses on CALIFA, showing the detector performance and presenting first results of the reaction studies.
