2K（2ν）-在Xe-124中捕获：37.7 kg x天暴露的数据处理结果
2K(2ν)-Capture in Xe-124: Results of Data Processing for an Exposure of 37.7 kg x day
摘要：
本文介绍了用大铜正比计数器对$^{124}$中的双中微子$2K$ -俘获进行实验研究的结果，该计数器是通过处理37.7公斤$\times$/天的辐照数据获得的。实验装置位于Baksan中微子天文台地下低本底实验室，深度为4900 m w.e.。选择有用信号的方法与一组独特的特性和事件拓扑结构相结合，使我们能够抑制感兴趣的能量区域中的背景。测定了$^{124}$中$2K(2ν)$ -捕获的新半衰期极限：T $_{1/2}\geq7.7\cdot10^{21}$年（90\% C.L.）。
英文摘要：
The results of the experimental search for two-neutrino $2K$-capture in $^{124}$Xe with a large copper proportional counter obtained by processing the data for an exposure of 37.7 kg$\times$day are presented. The experimental setup is located at the Underground Low-Background Laboratory of the Baksan Neutrino Observatory at a depth of 4900 m w.e. The combination of methods of selection of useful signals with a unique set of characteristics and the event topology taken into account allowed us to suppress the background in the energy region of interest. A new half-life limit for $2K(2ν)$-capture in $^{124}$Xe was determined: T$_{1/2}\geq7.7\cdot10^{21}$ yrs (90\% C.L.).
