We report the Chandra detection of X-ray emission spatially coincident withthe kpc-scale radio bubbles in the nearby (D_L ~ 31 Mpc) AGN-starburst galaxyNGC 6764. The X-ray emission originates in hot gas (kT ~ 0.75 keV), which mayeither be contained within the radio bubbles, or in a shell of hot gassurrounding them. We consider three models for the origin of the hot gas: (1) astarburst-driven galactic wind, (2) shocked gas associated with the expandingradio bubbles, and (3) gas heated and entrained into the bubbles by jet/ISMinteractions in the inner AGN outflow. We rule out a galactic wind based onsignificant differences from known galactic wind systems. The tightcorrespondence between the brightest X-ray emission and the radio emission inthe inner outflow from the Seyfert nucleus, as well as a correlation betweenX-ray and radio spectral features suggestive of shocks and particleacceleration, lead us to favour the third model; however, we cannot firmly ruleout a model in which the bubbles are driving large-scale shocks into the galaxyISM. In either AGN-driven heating scenario, the total energy stored in the hotgas is high, ~10^56 ergs, comparable to the energetic impact of low-power radiogalaxies such as Centaurus A, and will have a dramatic impact on the galaxy andits surroundings.
