A java library to Compute Compton, Raleigh, Photoelectric and Pair Production Cross sections
MuMassCalculator is derived from the NIST XCOM web application used to calculate photon cross sections for scattering, photoelectric absorption and pair production, as well as total attenuation coefficients, for any element, compound (Z ≤ 100), at energies from 1 keV to 100 GeV.

Notes:
Unlike XCOM, MuMassCalculator does not support mixtures.
MuMassCalculator was developed with JavaSE-1.8 (64-bit) and tested in the Eclipse IDE and as an ImageJ PlugIn with ImageJ 1.53k
MuMassCalculator has no ImageJ dependencies.
