Popis: A rotational band of nineteen transitions with a moment of inertia ${\mathfrak{J}}_{\mathrm{band}}^{(2)}$ of $84{\ensuremath{\hbar}}^{2}$ ${\mathrm{MeV}}^{\ensuremath{-}1}$ has been observed in $^{152}\mathrm{Dy}$. The band feeds into the oblate yrast states between ${19}^{\ensuremath{-}}$ and ${25}^{\ensuremath{-}}$ and it is proposed that the lowest member of the band has a spin of ${22}^{+}$ and thus the band extends up to $60\ensuremath{\hbar}$. It is identified as the yrast superdeformed band and its intensity accounts for the whole of the ridge structure seen previously in continuum ${E}_{\ensuremath{\gamma}}\ensuremath{-}{E}_{\ensuremath{\gamma}}$ correlations.
