Abstract
A constant stress Couette cell rheometer has been modified to measure simultaneously the viscometric properties and neutron scattering inten sities from the NIST Center for Neutron Research (NCNR) small angle ne utron scattering (SANS) spectrometers. The apparatus was constructed t o complement scattering radiation experiments of solutions under shear . The apparatus is capable of high accuracy measurements with viscosit ies that can range over about ten orders of magnitude. Sample plots sh owing simultaneous measurements of the viscosity and the anisotropic s cattering patterns from micellar solutions are presented. The apparatu s is easily adapted for light scattering.
