Incoherent elastic scattering cross section
Elastic scattering can be treated in the incoherent approximation for partially ordered systems such as ZrHx and polyethylene. The integrated cross section can be obtained as:
\[\sigma(E,T) = \frac{\sigma_b}{2} \left ( \frac{1 - e^{-4EW'(T)}} {2EW'(T)} \right ) \]where \(\sigma_b\) is the characteristic bound cross section, and \(W'(T)\) is the Debye-Waller integral divided by the atomic mass in [eV\(^{-1}\)].
