    "abstract": "We investigate the structure of the instantaneous Bethe-Salpeter equation for\n\\(q\\bar{q}\\)-bound states in the general case of unequal quark masses and\ndevelop a numerical scheme for the calculation of mass spectra and\nBethe-Salpeter amplitudes. In order to appreciate the merits of the various\ncompeting models beyond the reproduction of the mass spectra we present\nexplicit formulas to calculate electroweak decays. The results for an explicit\nquark model will be compared to experimental data in a subsequent paper",
