Gordon in 1958. In this sense, a radar beam scattering off electrons in the ionospheric plasma produces an incoherent backscatter.
WebJul 26, 2024 · Coherent intermediate scattering function from simulations. The sum of sine terms is mathematically zero if you note that taking the ensemble average <...> requires random sampling of the directions of vector Q. Ususally true for liquids, this isotropic sampling over different solid angles causes each sine term to vanish. WebFs(q, t) = 1 N ∑ α ∈ H e − iq ⋅ ˆrα ( 0) eiq ⋅ ˆrα ( t) . [3] Fs(q, t) is referred to as intermediate scattering function and ˆrα is the position operator of hydrogen atom α in the sample. The symbol … denotes here a quantum ensemble average, and the intermediate scattering function is a quantum time correlation function.
