Abstract: | Measurements of the elastic scattering π−−12C between 120 and 280 MeV permit an investigation of the Kisslinger-Ericson π-nuclear optical potential around the (3, 3) resonance. For this analysis nearly all parameters are assumed to be fixed by other reliable measurements resp. evaluations, apart from two parameters for the strength of the gradient potential (complex co). We explore the lines of equal χ2 in the complex co plane and find two solutions. One of them can be interpreted as the physical solution. |
