Probing the Structure of Nucleons in the Resonance Region with CLAS at Jefferson Lab.

摘要

The physics of electromagnetic excitation of nucleon resonances and of their relevance in nucleon structure studies are discussed. Preliminary data from the CLAS detector on the N-Delta(1232) transition multipoles, the helicity amplitudes of the N*(1535), and the search for so-called 'missing resonances' at Jefferson Lab are presented.
