The angle between the axis of symmetry of nonisotropic inhomogeneities and the surface of a bulk sample is sometimes unknown. This angle may be determined by fitting small‐angle neutron scattering (SANS) data taken at two or more different sample inclination angles. The feasibility of this technique is verified by analyzing SANS data taken at different tilt angles from a well characterized hot‐stretched (partially deuterated) polystyrene sample.
