Gamma-ray spectrometry in the decay of (194)Ir to (194)Pt.
As a complement to a resent high-resolution spectrometric investigation of the decay of (194)Au to levels of (194)Pt, a similar study has been undertaken of the decay of 19-h (194)Ir to (194)Pt. The two decays populate a similar set of levels in (194)Pt, and so the complementary investigations with similar resolution and efficiency permit a direct comparison of the two data sets. Overall there is excellent agreement between the energies of the common γ-ray transitions and also between the deduced energies of the excited states in (194)Pt. The (194)Ir half-life has been remeasured to be 19.20(2)h.
