We present Gemini GMOS IFU observations of six massive ($M_\star\geq10^{11} \M_\odot$) A-star dominated post-starburst galaxies at $z\sim0.6$. Thesegalaxies are a subsample of the SQuIGG$\vec{L}$E Survey, which selectsintermediate-redshift post-starbursts from the Sloan Digital Sky Surveyspectroscopic sample (DR14) with spectral shapes that indicate they haverecently shut off their primary epoch of star formation. Using $H\delta_A$absorption as a proxy for stellar age, we constrain five of the galaxies tohave young ($\sim 600$ Myr) light-weighted ages at all radii and find that thesample on average has flat age gradients. We examine the spatial distributionof mass-weighted properties by fitting our profiles with a toy model includinga young, centrally concentrated burst superimposed on an older, extendedpopulation. We find that galaxies with flat $H\delta_A$ profiles areinconsistent with formation via a central secondary starburst. This impliesthat the mechanism responsible for shutting off this dominant episode of starformation must have done so uniformly throughout the galaxy.
