[Principle and application of scattering power function method in X-ray fluorescence analysis. II. Incoherent scattering radiation].
It was discovered that the relationship between mass attenuation coefficient and incoherent scattering is not an inverse proportion but a power function in a wide range of matrix compositon. Experimental results are in good agreement with this theoretical predition. A new method is recommended for matrix absorption correction according to the discovery and used for the determination of microelement Sr in geological samples as an application example. The accuracy of the results of heavy absorption samples obtained by this method is much better than those obtained by the traditional scattering internal method.
