| Abstract [eng] |
The paper consists of seven theoretical and two experimental parts. Theoretical part overviews the classification of solids, the structure of materials and quartz, defects of crystals, the methods of structure research, the usage of Bragg’s law and X - rays fore defect’s research, and it also analyses the method of X - rays structural analyses. Experimental part includes the explanation of X - rays diffractive spectrum spike’s intensity connection with grating periodicity’s fluster. It also includes the research results and analyses of diffractive spectrum spike intensity dependences on X - rays generated dotted defects in quartz grating during irradiation. Research results: 1. During irradiation the intensity of quartz diffractive spectrum spikes changes. While the temperature increases this intensity change decreases. 2. While intensity changes, the angle adequate to diffractive spectrum maximum changes too, and together with it – interplane distance d. 3. Quartz grating average quadrate deviation’s change during irradiation is opposite to intensity change. 4. The concentration of dotted defects in quartz crystal increase when the intensity decreases or vice versa. But their change as and grating’s average quadrate deviations, decrease when quartz crystal is under heating if at the same time the intensity decreases. After analyzing the results of the research it is possible to make a conclusion that X - rays diffractive spectrum spike’s intensity depends on: 1. Defect’s concentration in quartz crystal; 2. Temperature, where the crystal is in. |
