Excitation of the Δ resonance in heavy ion charge exchange reactions

Abstract Results on the Δ excitation by heavy ion charge exchange are presented. 900 MeV per nucleon 12 C, 16 O, 20 Ne and 1100 MeV per nucleon 12 C have been used. The Δ excitation strength depends on the projectile — ejectile nature and on the incident energy. The role of the target mass is also discussed. The peak for the Δ in nuclei is energy shifted from the free Δ peak.
