The evolution of globular clusters is modeled in a detailed Fokker-Planck calculation and is followed well beyond core collapse. The model includes the heating effects on the cluster caused by the dynamical formation and evolution of binaries, captured in three-body encounters and hardened by interactions with passing stars. As expected, energy generation by binaries reverses core collapse at sufficiently high central densities and drives a reexpansion of the core. The previous findings of Sugimoto and Bettwieser (1983) that this expansion is unstable to the development of large-amplitude oscillations in the central density and core radius. The implications of the results for the long-term evolution of globular clusters, are discussed.
