title: Measurements of 64Cu and 68Ga half-lives and γ-ray emission intensities.
abstract: The (64)Cu and (68)Ga half-lives and γ-ray intensities were measured at IFIN-HH. The determination of absolute photon emission intensities was based on absolute activity standardizations carried out in this laboratory using the 4πPC-γ coincidence method. The half-lives were measured with a well-type ionization chamber. The photon emission intensities (relative and absolute values) were measured with a calibrated high-resolution γ-ray spectrometer. The results obtained and their uncertainties are discussed and compared with values of other authors.
