KRUSCHE, BERND 2012 <jats:p> A diverse experimental program for the study of the photoproduction of mesons off nuclei has been carried out - and is still running - at the Mainz MAMI and Bonn ELSA electron accelerators with the TAPS, Crystal Barrel, and Crystal Ball calorimeters. It is motivated as a detailed study of the in-medium properties of hadrons and the meson - nucleus interactions. Typical examples for the in-medium behavior of vector mesons (ω), scalar mesons (σ), and nucleon resonances ( P <jats:sub>33</jats:sub>(1232), S <jats:sub>11</jats:sub>(1535), D <jats:sub>15</jats:sub>(1520)) are discussed. Special attention is paid to meson - nucleus final state interactions. </jats:p> application/pdf https://sonar.ch/global/documents/247454 eng info:eu-repo/semantics/altIdentifier/doi/10.1142/s0217751x07035598 info:eu-repo/semantics/altIdentifier/issn/0217-751X info:eu-repo/semantics/openAccess International Journal of Modern Physics A. - World Scientific Pub Co Pte Lt. - 2007, vol. 22, no. 02n03, p. 406-415 Nuclear and High Energy Physics Astronomy and Astrophysics Atomic and Molecular Physics, and Optics IN-MEDIUM PROPERTIES OF HADRONS http://purl.org/coar/resource_type/c_6501
