scattering

 [skat´er-ing]
a change in the direction of motion of a photon or subatomic particle as the result of a collision or interaction.

scattering

Etymology: ME, scateren
a change in the direction of photons caused by the interaction between photons and matter. In coherent scattering, an incident photon interacts with matter and excites an atom, causing it to vibrate. The vibration causes the photon to scatter. Also called Thompson scattering, unmodified scattering. In Compton scattering an incident photon interacts with an orbital electron, transferring some of its energy to that electron. The electron is ejected, and the photon is scattered.

In particular, we assigned some deviations (rad) from the nominal (mid) values of superelevation (e), deflection angle ([alpha]) and time employed to cover input variables of residual circumference ([t.
6) involves deviation from three input parameters such as deflection angle ([alpha]) (varying from [0.
The receiver can receive most of the energy just ensure the incident within a particular deflection angle.
The magnitude of the under-measurement increased with increasing deflection angle, as expected.
Clearly, the advantage of the J&C model (and of the proprietary version of MW&B) is in its use of measured dimensions of the deformed plate, particularly the deflection angle, deflection depth, and deformed bore diameter.
Second, models used to predict bent plate flow rate errors should include measured dimensions of the bore diameter (and deflection angle, if required) of the bent plate to be accurate.
SwRI staff provided guidance to Kelley on the desired plate deflection angles and shapes.
Differences in vertical coordinates (shown in example in the figure) were used to calculate deflection angles and deflection depths.
A swing-arm protractor was used to measure all plate deflection angles.
For daily triggering to discrete positions, the collector is rotated about its tilted axis twice per day to the deflection angles [+ or -][Chi] as shown in Fig.
The average daily gain is shown to vary with the collector tilt and deflection angles, and is assessed over hourly, monthly and seasonal periods.
