title: Standardisation and measurement of the decay scheme data of 237Np
abstract: Within the framework of a EUROMET project, a solution of 237Np/233Pa at equilibrium has been standardised by 4pi(PC)-gamma counting. An intrinsic Ge spectrometer was employed to measure relevant gamma-ray emission probabilities. Good agreement was obtained for those pertaining to the decay of 233Pa, but not for the gamma-ray emissions following the decay of 237Np. The cause of such discrepancies is discussed.
