The transition quadrupole moments ${Q}_{t}$ for the superdeformed band in ${}^{40}\mathrm{Ca}$ have been determined through thin-target Doppler-shift attenuation analyses. A best-fit value of ${Q}_{t}=1.30\ifmmode\pm\else\textpm\fi{}0.05$ $e\mathrm{b}$ is obtained when a single value is assumed for the entire band. Fitting separate quadrupole moments for in-band transitions decaying from the high-spin states and the presumably admixed low-spin states results in ${Q}_{t}(\mathrm{high}{)=1.81}_{\ensuremath{-}0.26}^{+0.41}$ $e\mathrm{b}$ and ${Q}_{t}(\mathrm{low}{)=1.18}_{\ensuremath{-}0.05}^{+0.06}$ $e\mathrm{b},$ respectively. ${Q}_{t}$ values extracted for individual transitions in a Doppler-broadened line-shape analysis also indicate smaller ${Q}_{t}$ values at lower spins. These results are consistent with the interpretation of this band as an eight-particle--eight-hole superdeformed band with a significant admixture of less-collective configurations at low spins.
