The ridge structure with ΔΕγ=± 30 keV, observed in the past in coincidence with protons emitted in the reaction 187 MeV 37Cl + 120Sn and attributed to an hyperdeformed nuclear shape in 152Dy, 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.
