orsopy.slddb.element_table package

Package containing all elemental data used for SLD calculations.

Main function is get_element(value) that returns an Element object for a given Z-number or identifier. The objects are stored in a dictionary for faster lookup as well as keeping the objects for each element the same.

Raw data imported from NIST https://www.nist.gov/pml/atomic-weights-and-isotopic-compositions-relative-atomic-masses The atomic weights data were published by J. Meija et al in Atomic Weights of the Elements 2013, and the isotopic compositions data were published by M. Berglund and M.E. Wieser in Isotopic Compositions of the Elements 2009. The relative atomic masses of the isotopes data were published by M. Wang, G. Audi, A.H. Wapstra, F.G. Kondev, M. MacCormick, X. Xu1, and B. Pfeiffer in The AME2012 Atomic Mass Evaluation.
