Abstract

The decay of 62 min Sn¹²⁸ separated from products of U²³⁵ thermal neutron fission and of its daughter 10.8 min Sb¹²⁸ was studied by γ and β-ray spectrometry and by γ-γ and β-γ coincidence measurements. The 62 min Sn¹²⁸ decay shows γ-rays at 44±1 keV, 72±2 keV, 497±6 keV and 570±10 keV, and β-rays at ≈ 0.70 and 0.80 MeV. The 10.8 min Sb¹²⁸ decay shows γ-rays at 320±3 keV, 754±10 keV (2γ-rays) and 1070±20 keV in coincidence with a β-ray at 2.45 MeV. Other β-transitions deduced from γ-ray intensities are discussed, and a decay scheme is proposed. Gamma rays of adjacent Sn and Sb isotopes are presented but have not been further investigated.
