Measurements of 64Cu and 68Ga half-lives and γ-ray emission intensities

The 64Cu and 68Ga 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.

► 64Cu and 68Ga studies are necessary for new nuclear medicine applications. ► Accurate needed nuclear decay data for these nuclides were measured. ► Half-life values were determined by using a 4πγ ionization chamber. ► Photon emission intensities were measured by γ-ray spectrometry. ► These new results will be used for future nuclear decay data evaluations.
