Abstract: In the foregoing a new approach to quark models within the context of the good old Schrödinger equation has been presented. Essential for the applicability to complicated hadronic systems involving many coupled channels was an approximative formulation with delta functions, which allowed to write down the S-matrix in closed form. Phenomenological realizations of the model have shown to be able to account for a multitude of experimental data in spite of the unconventional but simple form of the chosen interactions. These results also might put question-marks to the very detailed predictions of many single-channel quark models.
