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.

Precise measurement of the emission probability of the 543 keV gamma ray of 199Pt.

199Pt has been produced by neutron irradiation of enriched 198Pt (95.71%) metal powder, and precise measurements have been made of the gamma-ray emission probabilities by means of 4pibeta-gamma coincidence apparatus and a live-timed two-dimensional data-acquisition system. Daughter 199Au decays with a half-life of 3.

Determination of precise gamma-ray emission probabilities for 88Rb.

Precise gamma-ray emission probabilities of 88Rb have been measured by 4pi beta-gamma coincidence using a live-timed two-dimensional data-acquisition system. The absolute emission probabilities of the 898.1, 1836.
