0 M ay 1 99 9 Narrow deeply bound K − atomic states
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 ato...
متن کامل¯k-nuclear Deeply Bound States? ∗
Following the prediction by Akaishi and Yamazaki of relatively narrow K̄-nuclear states, deeply bound by over 100 MeV where the main decay channel K̄N → πΣ is closed, several experimental signals in stopped K reactions on light nuclei have been interpreted recently as due to such states. In this talk I review (i) the evidence from K-atom data for a deep K̄-nucleus potential, as attractive as V K̄ (...

متن کاملDeeply bound meson-nuclear states: theoretical concepts and strategies
This presentation reviews recent developments in the understanding of lowenergy pionand kaon-nucleon interactions as they relate to deeply bound pionic atoms and possible antikaon-nuclear bound states. A brief update is given on 1s states of pionic atoms, summarizing their theoretical interpretation based on in-medium chiral effective field theory. This is followed by a stateof-the-art discussi...
