I want to read the basic concepts of SANS, SAXS and SWAXS spectroscopy. So I am looking for any document or website that describe the basic concepts of above mentioned spectroscopic techniques.
Dear Sir. Concerning your issue about the basic concepts of SANS, SAXS and SWAXS spectroscopy . I think the following below links may help you in your analysis:
Hi, if you find it in your library, or convince them to acquire, I also recommend the book "Neutron, X-rays and Light. Scattering Methods Applied to Soft Condensed Matter", written in a very nice way by some of the greatest experts in the field. Check the link below. Cheers
SANS, SAXS and SWAXS are not spectroscopy. It are diffractometry.
From Wiki.
X-ray emission spectrum
When an electron from the inner shell of an atom is excited by the energy of a photon, it moves to a higher energy level. When it returns to the low energy level, the energy which it previously gained by the excitation is emitted as a photon which has a wavelength that is characteristic for the element (there could be several characteristic wavelengths per element). Analysis of the X-ray emission spectrum produces qualitative results about the elemental composition of the specimen.
X-ray scattering techniques (diffractometry)
are a family of non-destructive analytical techniques which reveal information about the crystal structure, chemical composition, and physical properties of materials and thin films. These techniques are based on observing the scattered intensity of an X-ray beam hitting a sample as a function of incident and scattered angle, polarization, and wavelength or energy.
