A diagrammatic representation of data on @[email protected] from large particles, obtained at different angles but at the same concentration, constructed by plotting $$\log _{10}\Delta R\left(\theta \right)$$ or $$\log _{10}P\left(\theta \right)$$ versus $$(\sin \frac{\theta }{2})^{2}$$ or $$q^{2}$$ and (usually) used for the evaluation of the @[email protected] $$\Delta R(\theta)$$ is the @[email protected], $$P\left(\theta \right)$$ the @[email protected], $$\theta$$ the @[email protected] and $$q$$ the length of the @[email protected]
