摘要：
Small-angle neutron scattering measurements were performed for sodium polystyrenesulfonate-D2O solutions. A steep upturn behavior was observed at very small-angle regions below 0.01 Angstrom(-1) which could not measured by our previous X-ray experiments. This upturn reflects the existence of ordered cluster and its size was estimated to be around 400 - 1000 Angstrom by Guinier, Debye-Bueche, and Pored analyses. Model calculations were also performed to estimated the number density of the clusters by using absolute scattering intensity.
