Data

The pyne.data module implements access to various different sets of fundamental nuclear data stored in the nuc_data.h5 HDF5 database. These include the following distinct datasets:

• Fundamental constants common to nuclear engineering problems
• Atomic mass data (JAEA)
• Natural isotopic abundance data (IUPAC2009)
• Energy/fission (ORIGEN-S)
• Gamma Energy/fission (ORIGEN-S)
• Simple cross sections (KAERI)
• Dose factors for air, inhalation, soil, ingestion, uptake in fluids and lungs (Hanford report)
• Coherent/incoherent/total bound scattering lengths (NIST)
• Fission product yield from WIMSD and NDS (IAEA)
• X-ray conversion coefficients (BNL)
• ENSDF decay and level data (BNL)
