The Tomonaga model for a system of parallel chains with the long range Coulomb interactions is investigated by the bosonization technique. The respective rôles of the screened long range and the bare intermediate range interactions are examined in the 2 k F CDW/SDW correlation function. The accurate expression for this latter function is derived in the weak-coupling limit.Nous étudions le modèle de Tomonaga pour un système de chaînes parallèles avec les interactions de Coulomb de longue portée, en utilisant la méthode de bosonisation. Les rôles respectifs de l'interaction écrantée à longue portée et de l'interaction nue à portée intermédiaire sont examinés dans la fonction de corrélation 2 kF CDW/SDW. Nous obtenons l'expression complète pou...
