Modules and Libraries

Nexus provides a couple of modules that add some basic functionalities and some libraries with predefined object definitions.

Modules

constants
Module with mathematical constants (nx.constants.inf, …), physical constants, like electron mass, speed of light, and so on, e.g. nx.constants.NuclearMagneton. See constants.
conversions
Module with functions to convert various properties into different units, e.g. nx.conversions.VelocityToGamma() or nx.conversions.WtToAt(). See conversions.
data
Module with functions to load and manipulate typical data sets, e.g. nx.data.load(). See data and Data processing tutorial section.
euler
Module with functions to work with Euler angles, e.g. nx.euler.TransformationMatrixToZYZEuler(). See euler.
theory
Module with functions for theoretical calculations, e.g. nx.theory.RecoilEnergy(). See theory.

Added in version 1.0.3.
tools
Module with some useful functions. See tools.

Added in version 1.2.0.

lib.moessbauer
Library with predefined MoessbauerIsotopes. The naming convention is ElementMassnumber e.g. nx.lib.moessbauer.Ir193. See moessbauer.
lib.energy
Library with predefined transition energies. For nuclear transitions the naming convention is ElementMassnumber e.g. nx.lib.energy.Eu151. For atomic transition it is ElementTransitionname e.g. nx.lib.energy.MoKalpha. See energy.
lib.material
Library with predefined Materials. For compounds and alloys the naming convention is Element1Relativeweight1… e.g. nx.lib.energy.Al2O3. For isotope enriched materials with typically 95% enrichment the conventions is Material_enriched e.g. nx.lib.energy.Fe_enriched. See material.
lib.distribution
Library with predefined Distributions. A variety of different distributions are included, e.g. nx.lib.distribution.Log(). See distribution.
lib.residuals
Library with predefined Residuals. A couple of different residual implementations are included, e.g. nx.lib.residual.Sqrt(). See residual.
