The format is a subset of the Generalized Nuclear Data Structure (GNDS) developed for storing nuclear reaction data. A C++ library dubbed "Property of Particles" (PoPs) has been developed to read particle data in the GNDS format. The PoPs library provides functions for reading in a GNDS particle database as well as for accessing a particle and its properties. 3.0 United States Lawrence Livermore National Laboratory LLNL-CODE-770377 2019-07-15 2019-07-16 false false Bret Beck Lawrence Livermore National Laboratory USDOE National Nuclear Security Administration (NNSA) AC52-07NA27344 true Lawrence Livermore National Laboratory (LLNL), Livermore, CA (United States) true C++ MIT License
