PeakCollection.Rayleigh_weight(plasma_state: PlasmaState, setup: Setup) → Array

This is the result from Wünsch [Wünsch, 2011], to calculate the Rayleigh weight for a plasma from multiple species.

\[W_R = \sum_{a, b} \sqrt{x_a x_b} (f_a + q_a) (f_b + q_b) S_{ab}\]

Where

• The sum runs over all pairs of atoms \(a\) and :math`b`.

• \(x\) is the number fraction of the ion species \(a\), and \(b\), respectively.

• \(f_x\) are the form factors, based on the plasma_state’s 'form-factors' model.

• \(q_x\) describe the screening by free electrons, which can be set via the plasma_state’s 'screening' model.

• \(S_{ab}\) is the static ion-ion structure factor, which has to be provided by the S_ii() method.
