Exchange attenuation of standing spin waves is calculated for an ultrathin magnetic of the order of exchange length thick. Because of the boundary conditions the wave vectors of spin waves in such films high values that are proportional to the inverse film thickness. The exchange attenuation at such wave vectors becomes dominant and can result in smearing of the standing spin wave spectrum.
