Abstract
We study those compatible couples of Banach spaces for which the compl ex method interpolation spaces are also described by the K-method of i nterpolation. As an application we present counter-examples to Cwikel' s conjecture that all interpolation spaces of a Banach couple are desc ribed by the K-method whenever all complex interpolation spaces have t his property.
