  A microscopic optical potential based on a chiral model is used as a starting
point for studying kaonic atoms levels. We add to this potential a
phenomenological part fitted to the experimentally known shifts and widths of
kaonic levels. This fitted potential is used to predict deeply bound atomic
levels, as well as nuclear levels. Comparison with the predictions of other
optical models found in the literature is done. Also the effects on the kaonic
atoms levels of certain known non-local contributions to the optical potential
are also analyzed.
