openmc.stats.muir(e0: float, m_rat: float, kt: float, bias: Univariate | None = None)[source]

Generate a Muir energy spectrum

The Muir energy spectrum is a normal distribution, but for convenience reasons allows the user to specify three parameters to define the distribution: the mean energy of particles e0, the mass of reactants m_rat, and the ion temperature kt.

Added in version 0.13.2.

Parameters:

  • e0 (float) – Mean of the Muir distribution in [eV]

  • m_rat (float) – Ratio of the sum of the masses of the reaction inputs to 1 amu

  • kt (float) – Ion temperature for the Muir distribution in [eV]

  • bias (openmc.stats.Univariate, optional) – Distribution for biased sampling.

Returns:

Corresponding normal distribution

Return type:

openmc.stats.Normal
