Gamma Radiation Emitted by ¹⁹⁸Ir

Abstract

The gamma rays accompanying the decay of 8s ¹⁹⁸Ir were studied with a Ge spectrometer. Transitions with energies (intensities) of 407.4±0.3 (100±7) and 507.0±0.3 (76±10) keV have been confirmed. Additional transitions in ¹⁹⁸Pt have been sought up to energies of 2700 keV; none has been observed. An upper limit of 15% is placed on the intensity of any new transition in ¹⁹⁸Pt with an energy above 700 keV.
