Strong-Interaction Effects inK-Mesonic Atoms

Abstract

The process of absorption in $K$-mesonic atoms is studied with special emphasis on the role of the $Y_0^{*}\mathrm{}\left(1405\right)\mathrm{}$ resonance. An effective $t$-matrix method is developed to incorporate the effects of the resonance. Detailed calculations of the absorption process, based on an independent-particle model of the nucleus, were made for selected nuclei. The results of these calculations are compared with available x-ray and emulsion data for moderate to heavy nuclei.
