| Abstract: | Using cranking techniques a variety of baryon observables are calculated within the framework of the chiral bag model. Effects from valence quarks, mesons and the quark Dirac sea are included. Results for the NΔ mass splitting and nucleon magnetic moments are found to be relatively insensitive to the bag radius. |
