✦ Synopsis

On the basis of a diffuswm equation iucludmg a permdic patenti&. exact express&w are given far the Iou~i~~a~ and transverse afusion parameters measured in uniaxial smectic phau?s by spin-echo NMR. For relatively bqh ~1ue.s of the ordering potential, an intrinsic AIrhenius factor appears in the defiition of the rate of jump across the smectic layers
