scattering cross section in a sentence
Examples
- The scattering of X-rays can also be described in terms of scattering cross sections, in which case is a convenient unit : 10 " 20 m 2 10 4 pm 2 } }.
- For a radially symmetric scattering potential, as in the case of the Coulomb potential, d \ Omega = 2 \ pi \ sin { \ Theta } d \ Theta, yielding the expression for the scattering cross section
- If we consider only s-wave scattering the differential cross section does not depend on the angle \ theta, and the total scattering cross section is just \ sigma = 4 \ pi | f | ^ 2.
- For light, as in other settings, the scattering cross section is generally different from the geometrical cross section of a particle, and it depends upon the wavelength of light and the permittivity, shape and size of the particle.
- For his doctoral thesis, Lippmann collaborated with Schwinger to produce the Lippmann-Schwinger equation, an integral equation formulation of the Schr�dinger equation intended for the calculations of scattering cross sections since the required boundary conditions are implicit in the formalism.
- Various mathematical forms such as Gamma function, lognormal or exponential forms are usually used to model the DSD . Mie or Rayleigh scattering theory with point matching or t-matrix approach is used to calculate the scattering cross section, and specific rain attenuation.
- This is the probability of reaching the screen if none were scattered, lessened by an amount ( 4 \ pi / k ) \ operatorname { Im } [ f ( 0 ) ], which is therefore the effective scattering cross section of the scatterer.
- Gas-cooled fast reactors have been the subject of research as well, as helium, the most commonly proposed coolant in such a reactor, has small absorption and scattering cross sections, thus preserving the fast neutron spectrum without significant neutron absorption in the coolant.
- So in this case the total scattering cross section is equal to the area of the circle ( with radius r + R ) within which the center of mass of the incoming sphere has to arrive for it to be deflected, and outside which it passes by the stationary scattering center.
- The program had technical achievements as well, such as developing high-strength fibers, and carbide coatings for Lithium Hydride, which has a large scattering cross section for fast and thermal neutrons was found to perform well with low mass compared to older Boron Aluminum Titanium Hydride ( BATH ) shields.
