摘要
A search for various double electron capture modes of Se-74 has been performed using an ultralow background Ge-detector in the Felsenkeller laboratory, Germany. Especially for the potentially resonant transition into the 1204.2 keV excited state of Ge-74 a lower half-life limit of 0.70 x 10(19) yr (90% credibility) has been obtained. Serious concerns are raised about the validity of obtained Se-74 limits in some recent publications.
