The inelastic electron-electron scattering rate in strongly coupled qu
antum wells is investigated. Both intrasubband and intersubband scatte
ring processes are considered. The theoretical results are compared wi
th experimental data obtained from the analysis of the resistance reso
nance measured on GaAs/AlxGa1-xAs heterostructures in the presence of
an in-plane magnetic field. A good agreement with the theoretical curv
es is obtained. The range of validity of the picture presented is disc
ussed critically.
