AB  - The sum-energy spectrum of two correlated electrons emitted in nonsequential 
      strong-field double ionization (SFDI) of Ar was studied for intensities of 0.3 to 
      2x10;14 W/cm;2. We find the mean sum energy, the maximum of the distributions 
      as well as the high-energy tail of the scaled (to the ponderomotive energy) 
      spectra increase with decreasing intensity below the recollision threshold (BRT). 
      At higher intensities the spectra collapse into a single distribution. This 
      behavior can be well explained within a semiclassical model providing clear 
      evidence of the importance of multiple recollisions in the BRT regime. Here, 
      ultrafast thermalization between both electrons is found occurring within three 
      optical cycles only and leaving its clear footprint in the sum-energy spectra.
