Detailed Description

Sample the number of scintillation photons to be generated.

This populates the GeneratorDistributionData used by the ScintillationGenerator to generate optical photons using post-step and cached pre-step data.

The post-step speed is calculated from the particle's energy after continuous slowing down but before the particle loses energy in a discrete interaction.

The mean number of photons is a product of the energy deposition and a material-dependent yield fraction (photons per MeV). The actual number of photons sampled is determined by sampling:

• for large (n > 10) mean yield, from a Gaussian distribution with a material-dependent spread, or
• for small yields, from a Poisson distribution.
