bragg spacing? how does it differ from d-spacing? and where does q fit in? And finally are all of these directly related to the repeat distance?
X-ray scattering is a technique used to study the structure of materials by measuring the scattered X-rays produced when a beam of X-rays is directed at a material.
Bragg spacing is the distance between two consecutive crystal planes in a material. It is named after William Henry Bragg, who first described this phenomenon in 1912.
D-spacing, also known as lattice spacing, is the distance between two adjacent lattice planes in a crystal. It is often used to characterize the structure of materials using X-ray diffraction.
Q, also known as the momentum transfer, is a measure of the difference in momentum between the incident X-ray beam and the scattered X-rays. It is used to determine the size and spacing of particles in a material.
The repeat distance, also known as the unit cell length, is the distance between identical points on two adjacent unit cells in a crystal lattice. It is used to describe the periodicity of a crystal structure and can be calculated using the Bragg equation.
