Abstract
The reaction 40Ca(n, γ 0) 41Ca has been studied in the neutron energy range 20 28 MeV, where the isovector giant quadrupole resonance is expected. Interference between El and E2 radiation gives rise to a fore-aft asymmetry of the emitted γ-rays. The measured asymmetries are compared with calculations based on the direct-semidirect capture model. Good agreement with the experimental data is obtained assuming an isovector E2 resonance located at 32 MeV with a strength exhausting about 35%, of the isovector sum rule. This corresponds to the full strength of the T < component.
