Abstract
Low-energy kaon-nucleus interaction has been considered in the framework of multiple scattering theory as formulated by Watson and by Kerman, McManus, and Thaler. A kaon-nucleus optical potential of the shape of nuclear density is shown to follow from theory under the assumption that the nuclear excited states may be neglected and that the range of the underlying microscopic $\overline{K}N$ interaction is small in comparison with the nuclear radius. The depth of the effective potential is a nonlinear function of the $\overline{K}N$ scattering lengths and depends upon a single parameter related to the unknown range of the $\overline{K}N$ interaction. This parameter has been adjusted to the available kaonic atom data. The resulting potential has been used to evaluate the kaonic atom level shifts and widths and the calculated quantities are compared with experiment.NUCLEAR REACTIONS Optical potential derived and applied to evaluate kaonic atoms level shifts.
