Validation of Geant4 Atomic Relaxation against the NIST reference data

The validation of Geant4 with respect to authoritative reference data is a critical issue, fundamental to establish the predictive capabilities of Geant4-based simulations. We present the results of a series of comparisons for the evaluation of Geant4 atomic relaxation package with respect to the National Institute of Standards and Technologies (NIST) reference data.
