Highly precise measurements of the relative gamma-ray intensities for 56Mn and 72Ga.
Precise relative gamma-ray intensities of 56Mn and 72Ga produced by neutron irradiation of natural Mn3O4 and enriched 71Ga2O3 (99.8%) were measured by an HPGe detector with highly-precisely calibrated detection efficiencies. As both nuclides exhibit no beta branch to the ground state, the absolute emission probabilities of the 846.8 keV gamma ray for 56Mn and 834.0 keV gamma ray for 72Ga were determined to be 0.9888+/-0.0014 and 0.9553+/-0.0005, respectively.
