Kaonic atoms and Λ(1405)

Studies of Λ (1405) in Σπ decay channels are briefly presented and the related uncertainties indicated. The advantages of measurements in the \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$\overline{K}$\end{document}N channel are stressed. Two methods: studies of upper levels in K-mesic atoms and radiative decays from the hydrogen atom to Λ (1405) are discussed.
