Narrow deeply bound $K^{-}$ atomic states

Abstract

Using optical potentials fitted to a comprehensive set of strong interaction level shifts and widths in $K^{-}$ atoms, we predict that the $K^{-}$ atomic levels which are inaccessible in the atomic cascade process are generally narrow, spanning a range of widths about 50 - 1500 keV over the entire periodic table. The mechanism for this narrowing is different from the mechanism for narrowing of pionic atom levels. Examples of such `deeply bound' $K^{-}$ atomic states are given, showing that in many cases these states should be reasonably well resolved. Several reactions which could be used to form these `deeply bound' states are mentioned. Narrow deeply bound states are expected also in $\bar{p}$ atoms.
