Based on GOE sparse matrices, a model for decay‐out of superdeformed bands is formulated, with focus on the degree of chaoticity of the spectrum of normally deformed states, to which the superdeformed band couples at decay‐out. By means of the effective dimensionality parameter, the spectrum may be varied between the two limiting situations of complete order and complete chaos. The model is applied to the measured distribution of transition strength of decay‐out γ‐ray lines in 194 Hg, and it is found that the normally deformed states should be closer to the chaotic than the ordered situation, with GOE‐type spectral correlations extending over at least 10 levels.
