Web29 jun. 2016 · In the MCNP model, the gamma sources are defined as energies with intensity factors. For , γ a and γ b have an intensity ratio of 1 to 1. MCNP does not trace the time of particles and therefore the 2 gamma photons are treated independently. WebThe examples below show a sample of pyMGeo source code and the corresponding MCNP geometry.
