The baryon octet and decuplet masses and Bethe-Salpeter vertex and wavefunctions are calculated in the ladder approximation to the quark exchangebetween a scalar or axialvector diquark and a constituent quark. Thesefunctions reflecting full Lorentz covariance are given in terms of an expansionin Gegenbauer polynomials. In the rest frame of the baryon, a complete partialwave decomposition of the Bethe-Salpeter wave function is performed. Theconfinement of quarks and diquarks is implemented via a parametrisation of thecorresponding propagators. We also discuss some aspects of the momentum routingin the ladder approximation to the Bethe-Salpeter equation. Numerical resultsfor the octet and decuplet masses with broken flavour SU(3) in the conservedisospin limit are presented.Comment: 36 pages, 10 figures, LaTeX-Style article using epsfig. Bug in  program code detected; numerical results changed slightly, i.e. on the order  of a few percent, conclusions are not change
