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 20111 Determination of gamma-ray emission probabilities per decay of Ga-682014 - KOSKINAS, MARINA F.; LACERDA, FLAVIO W.; MATOS, IZABELA T.; NASCIMENTO, TATIANE S.; YAMAZAKI, IONE M.; TAKEDA, MAURO N.; DIAS, MAURO S.Artigo IPEN-doc 09146 Cascade summing corrections for HPGe spectrometers by the Monte Carlo method2002 - DIAS, M.S.; TAKEDA, M.N.; KOSKINAS, M.F.Artigo IPEN-doc 11674 Application of Monte Carlo simulation to the prediction of extrapolation curves in the coincidence technique2006 - DIAS, MAURO S.; TAKEDA, MAURO N.; KOSKINAS, MARINA F.Artigo IPEN-doc 11675 Primary standardization of sup(72)Ga2006 - KOSKINAS, MARINA F.; MOREIRA, DENISE S.; TAKEDA, MAURO N.; SENEDA, JOSE A.; DIAS, MAURO da S.Artigo IPEN-doc 16120 Monte Carlo simulation to positron emitter standardized by means of 4'pi''beta'-'gamma' coincidence system - Application to sup(22)Na2010 - DIAS, MAURO S.; TONGU, MARGARETH L.O.; TAKEDA, MAURO N.; KOSKINAS, MARINA F.
