Abstract

To aid in the quantitative assay of 239Pu by means of γ-ray spectrometry, we have made precise measurements of the emission probabilities of six of the prominent γ-rays associated with the decay of 239Pu. The γ-ray emission rates were measured using calibrated Ge spectrometers. The decay-rate calibration was based on a measurement of the α-emission rate by NBS. α-Ray energies were also measured. For six precisely measured lines the energy values obtained are 51.624(1), 129.296(1), 203.550(5), 332.845(5), 375.054(3) and 413.713(5) keV and respective γ-ray emission probabilities are 27.1(5), 6.41(5), 0568(4), 1.547(12) and 1.455(9) photons per 105 decays. Relative γ-ray intensities were also determined for about 55 additional transitions.
