Light kaonic atoms: from "corrected" to "summed up" Deser formula

Abstract

Accuracy of "corrected Deser" and "summed up Deser" formulas was checked for the $K^{-}p$ and $K^{-}d$ systems. It was found that the last one is much more accurate and should be used for connection the $1s$ level shift to the corresponding scattering length.
