Measurements of both neutron differential scattering cross sections as well as neutron total cross sections from {sup 190,192}Os and {sup 194,196}Pt are presented. Extensive coupled channels analyses, based on the low-lying collective excitations of these isotopes, were performed. These measurements and analyses are able to discriminate among the many nuclear structure models that have been offered to interpret this mass region. Neutron scattering is shown to be a sensitive probe of the weakly coupled collective excitations that characterize this region. In addition to the nuclear structure information extracted from the coupled channels analyses, other surprising results are noted. The neutron scattering potential was found to saturate at low energy, in contrast to the linear energy dependence usually found in scattering studies.
