Inclusive (e,e’) electron scattering is an established tool in nuclear physics that provides insights in nuclear structure with high accuracy because of its pure electromagnetic nature. (e,e’γ) coincidence experiments preserve this strength of inclusive electron scattering while additional information, for example, γ-decay branchings of PDR/GDR and the interference of longitudinal and transversal components of low-lying electric dipole excitations are accessible. The existing (e,e’) setup at S-DALINAC was extended by a detector array consisting of 6 LaBr3:Ce detectors. In 2021 a successful (e,e’γ) measurement was conducted on a mid-heavy nucleus, 96Ru, for the first time. The main goal of this measurement was to study the B(M1,2ms+→21+) and B(E2,2ms+→01+) decay transition strengths of the 2ms+ state of 96Ru. Data were taken at excitation energies below and above the neutron separation threshold allowing a variety of physics cases to be studied. This talk will present the (e,e’γ) coincidence setup and preliminary results of the 96Ru measurement.
