WebScattering occurs when an X-ray photon interacts with one of the electrons of the absorbing element. If this collision is elastic (no energy is lost in the collision process), the scattering is said to be coherent (Rayleigh scattering). …. Then the scattering is said to be incoherent (Compton scattering). WebThe incoherent scatter radar (ISR) technique is a powerful ground-based tool used to measure various properties of the ionized part of the upper atmosphere called the ionosphere. All radars transmit radio waves at a target and receive much weaker waves generated when electrons, the lightest charged component of the target matter, …
