Employing Coincidence Doppler-Shift Attenuation Method approaches to inelastic ion-scattering experiments in the A≈100 mass region — •Anna Bohn, Elias Binger, Tobias Langel, Markus Müllenmeister, Sarah Prill, Michael Weinert, and Andreas Zilges — University of Cologne, Institute for Nuclear Physics, Germany

The A≈100 mass region is a major focus of current research on various nuclear structure phenomena, such as shape evolution and proton-neutron symmetry mixing. Several inelastic ion-scattering experiments have been performed on stable even-even nuclei [1–4], including Te, Sn, Pd, Ru, Mo, and Zr isotopes, at the SONIC@HORUS [5] setup at the University of Cologne. Fundamental properties such as nuclear-level lifetimes, level schemes, and spin information could be investigated. This contribution provides an overview of the most recent results and different analysis approaches employing the Coincidence Doppler-Shift Attenuation Method [1,4].
