| Abstract
| - Using small-angle neutron scattering and liquid integral equation theory, we relate thestructure factor of flexible dendrimers of fourth generation to their average shape. The shape is measuredas a radial density profile of monomers belonging to a single dendrimer. From that, we derive an effectiveinteraction of Gaussian form between pairs of dendrimers and compute the structure factor using thehypernetted chain approximation. Excellent agreement with the corresponding experimental results isobtained, without the use of adjustable parameters. The present analysis thus strongly supports theprevious finding that flexible dendrimers of low generation present fluctuating structures akin to starpolymers.
