WebbThere are various forms of X-ray scattering techniques, including small- and wide-angle X-ray scattering (SAXS and WAXS), which differ by measuring the scattered X-rays at small (2θ=0-5°) or wide angles (2θ >5°), respectively. While SAXS and WAXS work widely with powder or liquid samples, ...
Webb1 aug. 2024 · A small-angle scattering experiment conventionally measures the intensity of scattered radiation versus the magnitude of the scattering vector q; the latter equates to (4π/λ)sinθ, where 2θ is the scattering angle and λ is the wavelength of the incident radiation.
