Low--Energy Kaon--Nucleon Interactions and Scattering at DA$\Phi$NE

Abstract

We present in this contribution the basic formulæ for the analysis of low--momentum charged-- and neutral--kaon interactions in hydrogen, including as well a (brief) description of the problems left open by past experiments, and of the improvements DA$\Phi$NE can be expected to offer over them. Interactions in deuterium and other light nuclei will be only briefly mentioned, and only in those respects touching directly upon the more ``elementary'' aspects of kaon--nucleon interactions.
