Function Documentation

float Acts::computeEnergyLossLandauSigma(const MaterialSlab &slab, int pdg, float m, float qOverP, float q = UnitConstants::e)

Compute the Gaussian-equivalent sigma for the ionisation loss fluctuations.

This is the sigma paramter of a Gaussian distribution with the same full-width-half-maximum as the Landau-Vavilov-Bichsel distribution. The computations are valid for intermediate particle energies.
