Published {ital n}-{sup 209}Bi elastic differential cross-section, analyzing power, and total cross-section data in the energy range from 1.5 to 14 MeV were analyzed via a phase-shift analysis in order to find out whether these data show similar, unexplained resonance structures as observed recently for {ital n}-{sup 208}Pb scattering. Although the {ital n}-{sup 209}Bi and {ital n}-{sup 208}Pb data are very similar, some of the phase shifts are quite different for the two systems. Only one resonancelike structure was observed for {ital n}-{sup 209}Bi scattering in the excitation energy range from 9 to 18 MeV compared to eleven in the {ital n}-{sup 208}Pb system, implying that {ital n}-{sup 209}Bi data are probably more suitable than the classical {ital n}-{sup 208}Pb system for detailed mean-field analyses approached through dispersion-relation optical models.
