    "abstract": "Photoexcitation of the nucleon is studied in the framework of the constituent\nquark model with nonrelativistic quark-quark interactions. Utilizing the\ndominance of the pairwise structure of the relevant three-quark potential, the\nbound and excited state wave functions have been constructed using the\nFaddeev-type Integrodifferential Equation Approach. The method is based on the\nHyperspherical Harmonics expansion and takes two-body correlations exactly into\naccount and therefore reliable wave functions, required in photo processes, can\nbe obtained. The integrated photoabsorption cross sections for the E1-and\nM1-transitions are calculated and compared with experimental values as well as\nwith those of other theoretical calculations. Our results, in overall, are in\ngood to very good agreement with the experimental values.",
