Nous prouvons une estimation du type ∥q 1 -q 2 ∥ L ∞ ≤Cφ(∥A q 1 -A q 2 ∥ R,3/2-1/2 ), où A q i (ω,θ), i=1,2 est l’amplitude de “scattering” relative au potentiel à support compact q i (x) à un niveau d’énergie fixée k= const., où φ(t)=(-lnt) -δ , 0<δ<1 et ∥·∥ R,3/2-1/2 est une norme définie.

We prove an estimate of the kind ∥q 1 -q 2 ∥ L ∞ ≤Cφ(∥A q 1 -A q 2 ∥ R,3/2-1/2 ), where A q i (ω,θ), i=1,2 is the scattering amplitude related to the compactly supported potential q i (x) at a fixed energy level k= const., φ(t)=(-lnt) -δ , 0<δ<1 and ∥·∥ R,3/2-1/2 is a suitably defined norm.
