By applying two separate experimental methods the parity of the two components of the n-doublet of the X 211,,z ground state ofN0 is determined. In the first method the assignment is made by simultaneously measuring one-and two-photon laser induced fluorescence spectra of the A \*E+ state and applyi
The coupling to light mesons leads to large widths and shifts of the energy of the excited states in the baryon spectrum from the predictions of the constituent quark model with three valence quarks. This coupling may be modeled by admixtures of sea-quark qqq(q q) n configurations in the resonances.
