DerK-Konversionskoeffizient f�r den Zerfall des Os191m

TheK conversion coefficient near threshold of theM3 transition in191Os

“…The transition energy is only 0.5 keV above the K electron binding energy. Some speculations [1,2] have been made belonging to a steep descent of the M3 K conversion coefficient. Therefore, a precise measurement of the K conversion coefficient ~K tests internal conversion theory in the hitherto unexplored region very close to the energy threshold.…”

“…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.…”
