Abstract
A quark-diquark approximation is used to investigate the mass spectroscopy of the spin-1/2 baryons belonging to theSU(3)-flavor group in a nonrelativistic potential approach. The baryon spectra obtained are confronted with relativistic results and experimental data. Root-mean-square radii are also calculated.
