Abstract :
Electron cooling of heavy ions has been studied at the storage ring ESR over the whole range of ions up to bare uranium. Systematic measurements of the ion beam temperature evidence a dependence on the particle number which proves an equilibrium between cooling and heating by intrabeam scattering. Measurements of the longitudinal intrabeam scattering rate and of the longitudinal cooling force provide information about the longitudinal cooling times. Small deviations of the longitudinal cooling time from the theoretically predicted A/Z2 -dependence are found
