The s-wave repulsion and deeply bound pionic atoms: fact and fancy
E. Friedman · A. Gal · (Hebrew U. Jerusalem)
Abstract
Fits to a large data set of pionic atoms show that the `missing' s-wave repulsion is accounted for when a density dependence suggested recently by Weise is included in the isovector term of the s-wave pion optical potential. The importance of using large data sets is demonstrated and the role of deeply bound pionic atom states is discussed.
