Abstract: Applications (CSD) in various fields of industry, medicine, agriculture, and etc, is increasing. In this way, we can to determine the density of the target material by investigating the density of scattering photons. In medicine to identify tumor tissue to determine the extent of bone density in industry and agriculture to produce products with specific properties can be of use. If a sample is placed under tension or any changes in this case will change the shape of the distribution .the comparative method can be used to detect changes occurring the atomic structure and to determine the cause can be used. A typical density for any reason it has changed, the distribution of scattering will be change. By comparing how the new situation with scattering condition can be obtained information about the target material.
