Abstract
One of the major thrusts in hadronic physics targets more fully understanding the internal structure of the proton and neutron. The challenges presented in understanding nucleon structure are large, in part due to the complexity of this strongly interacting system and the presence of many broad and overlapping resonances. In order to better determine the reaction amplitudes for the production of these excited states, polarization observables are an essential tool. To this end, the CLAS detector at Jefferson Lab has been combined with polarized beams and targets to study excited nucleon states. The data obtained will provide measurements that are nearly complete descriptions of the reaction mechanism. These new measurements will allow for extraction of the reactions amplitudes in a nearly model-independent manner. An overview of the CLAS N* polarization program and recent results will be presented.
