Abstract: (Springer)
We calculate the masses of the nonstrange baryon resonances from a quark model with Coulomb and linear potential and hyperfine interaction. We treat the nonrelativistic problem with help of the variational method, the matrix of the spin-spin and tensor force is diagonalized within a harmonic oscillator supermultiplet. We find for the even and odd parity resonances good agreement with the spectrum of the particle data group and the results of the Karlsruhe-Helsinki phase shift analysis.- BARYON RESONANCE: NONSTRANGE
