Spectrum of nonsrange baryon resonances with high angular momenta

On the basis of the quark potential model the description of N- and δ-resonance spectra consistent at large and low values of the total momentum and mass is given. It is shown that the concepts of Regge trajectories and yrast states and yrast lines (taken from the theory of vibrational spectra of nucleui are quite useful in such description. The model provides a satisfactory fit to the experiment mass spectra in the entire experimentally investigated region. The energy spectra along the yrast lines are approximately linear in the total momentum
