Der Zerfall des Pt^195m und des Au¹⁹⁵

Abstract

The decays of Pt^195m(4.1 d) and Au¹⁹⁵ (192 d) have been investigated with a Ge(Li)-counter and a Ge(Li)-NaJ coincidence circuit. Theγ-spectrum of Pt^195m showed new lines with energies 239.5, 140.7 and 211.1 keV found earlier only in coulomb excitation experiments. Theγ-spectrum of Au¹⁹⁵ established a new level of Pt¹⁹⁵ at 199.8 keV with single particle character. These results led to a modified level scheme and modified reduced transition probabilities for the levels of Pt¹⁹⁵. By comparison of theγ-spectrum of Pt¹⁹⁵ m and Au¹⁹⁵ the ratios of electron capture branches of Au¹⁹⁵→Pt¹⁹⁵ decay have been determined.
