Search for linking transitions between the superdeformed and normal deformed states in 152Dy

The Eurogam I γ-ray array has been used to search for the linking transitions between the superdeformed (SD) and normal deformed states in 152Dy. Triple γ-ray coincidence data were analysed by employing the technique of summation of discrete γ-rays observed in coincidence with the transitions in the lowest energy (yrast) SD band in 152Dy. Several high energy peaks have been observed in the spectrum of the summed γ-rays and these are consistent with decay paths between the two structures. Analysis of these data and of single γ-ray spectra confirm that the decay is highly fragmented and that decays occur through a quasi-continuum of states between the SD and normal deformed minima.
