Abstract :

In this work, we present on some extent to experimental and theoretical study on the small angle scattering. Theoretical study of small angle scattering is explained more effectively. When the radiation is incident on the specimen, it deviates from its path is known as small angle scattering (SAS). SAS is very important technique to obtain detail information of bulk sample. In the SAS, partially crystalline or amorphous solids, liquids or gases are used as target. Moreover electrons, gamma rays, X–rays, are incident and target should be point object. But I consider only X–ray, so it is known as small angle scattering (SAXS). The improvement in the SAS instrumentation has recently enabled to get easy collection of datas. Distortion due to the X– ray detection system can be removed. The transverse dimension t of the coherence volume is also defined and discussed, as coherence volume is important to analyze datas. Out of three aspects like shape, polydispersity and packing, two properties must be known in order to explain rest of above properties.Characteristics of nanoparticles like gold can be known, if TEM method is included with the SAXS method, we will get best performance like information on morphological features ranging from microstructure to macro structure. Explanation of pin–hole collimated instruments, Bose– Hart instruments, slit collimated instruments are very popular due to their flexibility in terms of samples and easy availability suddenly increases. SAXS is used in multi phase system to explain scattering. There is also drawback of SAXS related to scattering intensity will be explained in paper.
