please mention the factors which effect the intensity of diffraction beam in X-ray diffraction..... explaine with reason.
I would hardly recommend to read any monography about XRD before asking such a fundamental question, or simply google or use Wikipedia. In books hundreds of pages are used to describe the separate factors and describe the complex interactions. If there is still some question you can use this platform for more specific questions.
In fact it is hard to answer on Researchgate to such a fundamental question. As Gert suggested, it is convenient that you first read one of the book on the topic.
Try this in a nutshell:
The intensity of a diffraction can be calculated if you know the position and the scattering power (number of electrons) of each atom in the crystal structure, according to the following (or similar) formula:
F(hkl) = SUM(j=1 to n) fj e 2pi (hxj+kyj+lzj)
Where:
• F(hkl) = Structure Factor representing the square root of the integrated intensity.
• fj = scattering power of the j atom at the angle 2θ
• Atom j is placed at the fractional coordinates xj, yj, zj.
Hence the definition of the Structure Factor: a physical entity attributed to each reflecting plane (hkl), providing a numerical expression for the entity of the cooperation to the reflection by all the atoms (from 1 to n) present in the unit cell in their respective structural positions (coordinates xj, yj, zj).
Romano! What about a single crystal with "extreme" preferred orientation? :-)
Adnan! I still struggle with that question each time I look at XRD reciprocal space data. There is no short-cut. No amount of "spoon-feeding" will be fruitful! You have to put your nose to the grind stone and imbibe some of those awesome standard XRD books. You may consider taking a refresher course in XRD as well to get the foundation right. Don't give up. It will come to you sooner or latter!
Learning about others' follies will help you avoid your own! Study the references! The book by B.D. Cullity is a popular reference. Compton & Allison is a classic! Include Andre Guinier!
If your question is related to XRD data then post it with full details to make the discussion interesting :-)
My attempt at rendering the basic principle in a nutshell for the use of a novice has evidently encountered some resistance. Never mind. Naturally, from a couple of definitions to the whole story there usually are a few books in between. However, a novice has to start somewhere and hopefully avoid getting immediately put off by a few hundred pages of hieroglyphics right at the start. After all the question, although overly naïf, was quite simple and I thought it deserved an answer as simple as possible, within the inherent complexity of the matter. Just to start off on the right path.
I wish good luck to Adnan Afzal and send my best wishes to Ravi Ananth and to all the other colleagues who joined this thread.
