Abstract:

A search for the γ decay of the Giant Dipole Resonance built on superdeformed (SD) nuclear configurations of 143Eu was made, using the reaction 110Pd(37Cl, 4n)143Eu at 165 MeV. Eight large BaF 2 scintillators and the NORDBALL array were used to measure high and low-energy γ-rays. The γ-spectrum gated by transitions populated by the SD states shows an excess yield at 7-10 MeV compared to the spectrum gated by transitions not populated by SD states. The comparison with statistical model predictions indicates that this excess most probably is due to γ-ray emission of the GDR built on superdeformed states.
