class openmc.data.IncoherentElasticAE(debye_waller)[source]

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

debye_waller (float) – Debye-Waller integral in [eV\(^{-1}\)]

Variables

debye_waller (float) – Debye-Waller integral in [eV\(^{-1}\)]
