| Abstract: | The γ decay of the giant dipole resonance (GDR) built on excited nuclear states has been measured in coincidence with the low-energy γ discrete transitions for the nucleus [sup 143]Eu. The reaction used was [sup 110]Pd([sup 37]Cl, 4n)[sup 143]Eu at a beam energy of 165 MeV. The EUROBALL spectrometer(for the measurement of discrete γ transitions) coupled with the HECTOR array (for high-energy γ-ray detection) has been used. The high-energy γ-ray spectrum in coincidence with superdeformed (SD) discrete transitions of [sup 143]Eu shows an "excess" between 9-12 MeV if compared with the one associated to cascades which do not pass through the SD configurations. Such an "excess" is in the energy region where one expects the low-energy component of the GDR strength function built on a SD state. The measured intensity can be reproduced by the statistical model assuming that the superdeformation survives only few MeV above the yrast line. A similar and consistent scenario has also been obtained by comparing the high-energy γray spectra of [sup 143]Eu in coincidence with its spherical (which is fed by the SD configuration) and its triaxial configuration (which is bypassed by the decay of the SD states).
