Lifetime Measurements of Spherical and Deformed States in 1f7/2 Nuclei

Lifetimes have been determined using the Doppler Shift Attenuation Method in the N ? Z nuclei 46 V and 48 V nuclei, populated with the reaction 28 Si on 24 Mg at 115 MeV and 24 Mg on 28 Si at 100 MeV using Au and Pb backed targets. The coexistence of spherical and deformed states in the middle of the 1f 7/2 shell is discussed. The B(E2) and B(M1) reduced rates agree very well with large scale shell model predictions

Search for hyperdeformed structures populated in the Cl-37+Sn-120 reaction by using EUROBALL III

The ridge structure with Delta E-gamma=+/- 30 keV, observed in the past in coincidence with protons emitted in the reaction 187 MeV Cl-37+ Sn-120 and attributed to an hyperdeformed nuclear shape in Dy-152, has been studied in a new experiment performed with the EUROBALL III array. The ridge is now observed in coincidence with transitions in the yrast superdeformed band of 152Dy but no discrete rotational bands have been identified

Search for hyperdeformed structures populated in the 37^{37}Cl+120^{120}Sn reaction by using EUROBALL III

The ridge structure with $\Delta$E$_\gamma$=$\pm$ 30 keV, observed in the past in coincidence with protons emitted in the reaction 187 MeV $^{37}$Cl + $^{120}$Sn and attributed to an hyperdeformed nuclear shape in $^{152}$Dy, has been studied in a new experiment performed with the EUROBALL III array. The ridge is now observed in coincidence with transitions in the yrast superdeformed band of $^{152}$Dy but no discrete rotational bands have been identified

Observation of double giant dipole resonance in fusion-evaporation reactions

The emission of two coincident energetic (E greater than or equal to8 MeV) gamma rays has been observed in the 187 MeV Cl-37 + Sn-120 reaction by using the cluster detectors of the EUROBALL III array. Those events are attributed to the decay of the double giant dipole resonance built on highly excited states
