Inelastic (e,e′γ) scattering from 12C and 92Zr nuclei — •Doris Jakubassa-Amundsen1 and Vladimir Ponomarev21Mathematisches Institut, LMU Muenchen — 2Institut fuer Kernphysik, TU Darmstadt

At the S-DALINAC there are electron scattering experiments in preparation which will concentrate on low-lying nuclear excitations and their subsequent radiative decay for beam energies around 70-100 MeV. By allowing for a clear separation from the background of high-spin states, such coincidence experiments are aimed at investigating nuclear structure properties of low-lying 2+ states of spin-zero nuclei. Within the QPM and the DWBA theory, we provide theoretical predictions for the excitation of the 21+ and 22+ states of 92Zr, but we also discuss the 21+ excitation of 12C which was pioneered in an early experiment in 1984. Particular emphasis will be laid on the 2+-subshell excitations, on the photon angular distributions and on the role of bremsstrahlung as a competing process to nuclear excitation and decay.
