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]
