Read X-ray mass attenuation coefficients for all materials and composition automatically from the NIST database.

Read X-ray Mass Attenuation Coefficients from NIST database

Read X-ray mass attenuation coefficients for all materials and compositions automatically from the NIST database and convert into other format.

Currently the program convert all of the data to Matlab scripts, which generates four variable: symbols - the short name of the materials zaid - the ratio of atomic number-to-mass Z/A, the mean excitation energy I, and the density ρ comp - composition in terms of different elements mac - mass attenuation coefficient table

There are 140 materials in total, with 92 elements and 48 compositions.
