The observation of radiative collisions in the strong-field regime is reported, specifically the multiphoton-microwave-assisted resonant collisional energy-transfer process Na(ns)+Na(ns)..-->..Na(np) + Na((n-1)p)+mh..nu.., where m is as high as 4. By use of a ''dressed-atom'' approach in a low-frequency (or adiabatic) approximation, a theoretical interpretation valid for the strong-field regime is given which is in good agreement with the present experimental results.
