Search for E2 Strength Below the Isoscalar Quadrupole Giant Resonance in 52Cr with Resonant Photon Scattering* — •O. Karg, J. Enders, P. von Neumann-Cosel, A. Richter, and S. Volz — Institut für Kernphysik, Technische Universität Darmstadt, 64289 Darmstadt, Germany
Motivated by the unusually large exhaustion of
the energy-weighted sum rule for isoscalar B(E2) strength below 10
MeV in 48Ca [1], we searched for E2 strength in another N =
28 nucleus, 52Cr. A nuclear resonance fluorescence
experiment was performed at the S-DALINAC using a bremsstrahlung
beam with an endpoint energy of 9.9 MeV. Experimental results and
a comparison to shell-model and quasiparticle-phonon model
calculations are presented.
