https://doi.org/10.1351/goldbook.P04429
The ratio of the intensity of radiation scattered at an @S05488@ $$\theta$$ to the intensity of radiation scattered at an @A00346@ zero, i.e. $$P\left(\theta \right)\equiv \frac{R\left(\theta \right)}{R\left(0\right)}$$. An alternative recommended symbol is $$P_{\theta }$$. Synonymous with particle scattering factor.
