[en] The spectrum of γrays decaying out of the superdeformed (SD) band in ¹⁹²Hg has a quasicontinuous distribution. Whereas methods to construct level schemes from discrete lines in coincidence spectra are well established, new techniques must still be developed to extract information from coincidences involving quasicontinuous γrays. From an experiment using Eurogam, we obtained impressively clean 1- and 2-dimensional γ spectra from pairwise or single gates, respectively, on the transitions of the SD band in ¹⁹²Hg. We investigated methods to exploit the 2-dimensional quasicontinuum spectra coincident with the SD band to determine the excitation energy of the SD band above the normal yrast line. No strong peaks were observed in the 2-γ sum spectra; only candidates of peaks at a 2-3 σ level were found. This suggests that 2-γ decay is not the dominant decay branch out of SD bands, consistent with the observed multiplicity of 3.2. We shall next search for peaks in sum-spectra of 3 γs
