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.
