| Resumen : | ABSTRACT: The use of reactions induced by the electromagnetic interaction such as photoproduction and electroproduction of mesons is an important tool for studying the electromagnetic properties of nucleon resonances which has played a significant role in the tests of quark models, such as the ratio of the electric quadrupole to the magnetic dipole transition amplitudes (EMR) in the processes \gamma N ---> \Delta(1232) and \Delta(1232) ---> \gamma N . In this work we will focus on the particular case of pion photoproduction to evaluate, analytically and numerically through an effective Lagrangian approach (ELA) model, physical observables such as the total cross-section and the multipole amplitudes which are compared with available experimental data to extract the relevant coupling constants of the nucleon resonances. |
