Parameters:

name (str, optional) – User label.
nuclide_composition (dict) – Dictionary mapping nuclide names (str) to atom densities (float).
element_composition (dict) – Dictionary mapping element names (str) to atom densities (float).
temperature (float, optional) – Temperature in Kelvin (default 293.6 K).

Returns:

The material object.

Return type:

Material
