Artigo IPEN-doc 24232 Disintegration rate and gamma-ray emission probability per decay measurement of Cu-642018 - YAMAZAKI, I.M.; KOSKINAS, M.F.; MOREIRA, D.S.; TAKEDA, M.N.; DIAS, M.S.The procedure followed by the Nuclear Metrology Laboratory (LMN) at the IPEN for the standardization of activity of 64Cu is described. The measurement was carried out in a 4π (PC) β-γ coincidence system. The activity per unit mass of the solution was determined by the extrapolation technique. The events were registered using a Time to Amplitude Converter (TAC) associated with a Multi-channel Analyzer. The gamma-ray emission probability per decay of the 1345.7 keV transition of 64Cu determined with a calibrated REGe gamma-ray spectrometer was (0.472±0.010) %, in agreement with the literature.Artigo IPEN-doc 16118 Determination of sup(198)Au X-rays emission probabilities2010 - MOREIRA, D.S.; KOSKINAS, M.F.; DIAS, M.S.; YAMAZAKI, I.M.Artigo IPEN-doc 16119 Determination of sup(51)Cr and sup(241)Am X-ray and gamma-ray emission probabilities per decay2010 - MOREIRA, DENISE S.; KOSKINAS, MARINA F.; YAMAZAKI, IONE M.; DIAS, MAURO S.Artigo IPEN-doc 16121 Primary standardization of sup(57)Co2010 - KOSKINAS, MARINA F.; MOREIRA, DENISE S.; YAMAZAKI, IONE M.; TOLEDO, FABIO de; BRANCACCIO, FRANCO; DIAS, MAURO S.
