Sažetak
The Crystal Ball Collaboration measured differential cross sections for pion-nucleon charge-exchange reaction at seven different pion momenta in the momentum region between 105 MeV/c and 180 MeV/c. When analyzed, these data will represent the highest-precision differential cross sections in this energy region. They will be essential for providing the necessary constrains on partial-wave analysis so that pion-nucleon sigma term can be extracted more reliably, and also provide a determination of the mass difference of the up and down quarks. Preliminary results for these differential cross sections are presented.
