Differential cross section for incoherent elastic scattering
The differential cross section for incoherent elastic scattering may be represented as:
\[\frac{d^2\sigma}{dE'd\Omega} (E\rightarrow E',\mu,T) = \frac{\sigma_b} {4\pi} e^{-2EW'(T)(1-\mu)} \delta(E - E') \]where \(\sigma_b\) is the characteristic cross section in [b] and \(W'(T)\) is the Debye-Waller integral divided by the atomic mass in [eV\(^{-1}\)].
- Parameters
