Pion Scattering at Energies above the delta Resonance

摘要

The Delta (1232) resonance dominates pion-nucleon scattering at energies below 300 MeV, the region in which pion-nucleus scattering has been well studied using spectrometers at the meson factories. Above this energy region few pion-nucleus scattering data exist. Recently, spectrometers at Brookhaven, LAMPF, KEK, and DUBNA have been used to obtain initial data for pion-nucleus scattering in this energy region. In this talk, we review some data that have been obtained using the LAS spectrometer at LAMPF.
