Uncertainty of Plutonium Isotopic Measurements with Microcalorimeter and High-Purity Germanium Detectors

“…Gamma-ray spectra were collected from seven plutonium standards whose isotopic compositions were well-known from separate mass spectrometry measurements [11], [12], [13]. These materials are summarized in Table I, where the isotopic composition has been decay-corrected to the time of measurement.…”
