Detailed Description

Sample energy loss from a gamma distribution.

This model is valid for heavy particles with small mean losses (less than 2 Bohr standard deviations). It is a special case of EnergyLossGaussianDistribution.

Constructor & Destructor Documentation

EnergyLossGammaDistribution()

CELER_FUNCTION celeritas::EnergyLossGammaDistribution::EnergyLossGammaDistribution ( Energy  mean_loss, EnergySq  bohr_var  )

inline

Construct from distribution parameters.

The model is only valid (rather, used in Geant4) for mean < 2 * stddev, but it is allowable to construct the sampler explicitly but outside this range, for analysis purposes.
