  "abstract": "We point out a distinguishing difference between constituent quark models based on one-gluon exchange and one-boson exchange dynamics. In the latter one, the P_11 nucleon resonance with predominantly symmetrical spatial wave function in the N=4 band gets strongly attracted such that it drops below some states in the N=2 band. Calculations of strong decay widths are presented in order to establish an identification with experimental states. Our results are relevant for the interpretation of the fourth P_11 resonance that was found in the partial wave analysis of the Zagreb group and recently discussed by Capstick et. al. in the framework of a model based on one-gluon exchange.",
