The scattering cross section
is related to the transmission of a beam through multiple scatterers.
In references 1 and 2 the measurement of scattering cross section
for polystyrene (PS) microspheres was discussed.
In the above expression [less than]C[greater than] is the average total scattering cross section
for a distribution of particles, while [less than][[C.
A commercial spectrometer with an integrating sphere (IS) detector was used to measure the scattering cross section
The important physical parameters are the differential scattering cross section
d[Sigma]([Omega])/d[Omega] of the scatterers, i.
Usually, it is necessary to convert these raw, instrument-specific, data into a quantity; the double differential scattering cross section
, that largely depends on the physics of the sample under investigation, as described in Sec.
The differential scattering cross section
is a function of direction defined by d[omega] and is defined by the following equation:
The neutron scattering cross section
is about a factor of 20 higher for the ortho configuration compared to the para configuration.
Since cold neutrons will depolarize in a liquid deuterium target in which the scattering cross section
is much larger than the absorption cross section, it will be necessary to quantify the loss of polarization before capture.
In effective-range theory, the singlet scattering cross section
Armstrong (12) noted that the ratios of elastic scattering cross section
and atomic mass to atomic number correlate fairly well.
Other major advantages in using electron scattering for crystallographic studies is that the scattering cross section
of matter for electrons is [10.
