K-Konversionskoeffizient nahe derK-Bindungsenergie:191m Os

Abstract

The K conversion coefficient of the predominantly M3 transition191mOs--191gOs Er= 74.37 keV has been measured to be ~K= 131 + 12. This differs from other measurements and from theoretical values.

TheK conversion coefficient near threshold of theM3 transition in191Os

“…Both, the late value published by Kirschner [3] (~r=131__12) and the result given by Campbell [2] (c~r= 75+__8) seem to be reliable, but they differ considerably, though they are based on the same experimental method. Uncertainties will be caused by the subtraction of the Os Kfl'z-and the Ir Kfi'tlines from the sum peak to yield the intensity of the weak 74.38 keV y-line, because a decomposition can not be made (Fig.…”

“…Meanwhile Kirschner [3] has remeasured the K conversion coefficient with the result c~/~= 131 _+ 12.…”

“…Until now only results of measurements with Ge(Li) X-ray detectors [1][2][3] used as spectrometers are available. Both, the late value published by Kirschner [3] (~r=131__12) and the result given by Campbell [2] (c~r= 75+__8) seem to be reliable, but they differ considerably, though they are based on the same experimental method.…”
