Experimental study of nuclear vorticity with the 12C(e,e’γ) reaction at the QCLAM electron spectrometer* — •Tobias Klaus, Sergej Bassauer, Andreas Krugmann, Peter von Neumann-Cosel, Norbert Pietralla, Vladimir Ponomarev, Maxim Singer, and Jochen Wambach — Institut für Kernphysik, TU Darmstadt

Experiments of inelastically scattered electrons in coincidence with real photons have the big advantage that the probe is purely electromagnetic and hence allow for nuclear structure studies of highest precision. We developed a setup for electron-γ-ray coincidence spectroscopy at the QCLAM electron spectrometer at the S-DALINAC. The first experiment is a study of γ-decay angular distributions in 12C in order to infer the vorticity of nuclear velocity fields in low-lying exited states. We present the experimental setup and discuss theoretical predictions for the velocity field distributions for the 21+ and 31 state. The 1T=1+ state at 15.11 MeV will be used to calibrate the setup for further experimental campaigns.
