(physics)
Process in which a particle undergoes a large number of collisions, and the total change in its momentum is the sum of the many small changes occurring during individual collisions.

The transmission is directly related to the spray concentration and errors caused by multiple scattering.
One of the most important approaches used to describe such collisions is the Glauber's multiple scattering theory (GMST) [2-4].
It assumes a random distribution of scatterers of the same size in the medium and neglects multiple scattering effects.
It is widely observed that in addition to absorption in these samples multiple scattering processes occur that affect the observed Raman intensities.

Chapters cover properties of radiation, the electromagnetic spectrum, reflection and refraction, radiative properties of natural surfaces, thermal emission, atmospheric transmission and emission, absorption by atmospheric gases, broadband fluxes and heating rates, radiative transfer equation with scattering, scattering and absorption by particles, and radiative transfer with multiple scattering.
Therefore to suppress depolarization due to multiple scattering in a pure deuterium target would require a thin, weakly-absorbing target of liquid orthodeuterium.
At the National Research Council in Ottawa, the group led by Dave Rogers, Iwan Kawrakow, has implemented improvements in both calculation accuracy using improved sampling of multiple scattering events, and in calculation speed using variance reduction techniques.
Under the assumption that no multiple scattering takes place, the correlation length [Zeta] can be determined from the slope and intercept of the linear extrapolation of the data from these Debye-Bueche plots:
These experiments and the accompanying theoretical work in solid-state physics demonstrate that, contrary to long-held assumptions, multiple scattering doesn't completely wash out the information carried by waves.
Inside the paper as an extremely complex media photons experience multiple scattering and the phase and polarization randomizes very quickly so that initially they don't affect much the energy transport.
