论文摘要
双重β衰变或暗物质的各种大规模实验基于氙气。当前的实验处于吨状态，但也有一些想法可以在未来的尺寸上进行更大的尺寸。在这里，我们研究了同位素$^{131} $ XE的潜力，以便对太阳能$ pp $中微子进行实时测量，除了经典的中微子 - 电子散射。改进的核模型用于确定$^{131} $ XE上的中微子的横截面。由于激发状态贡献的更新估计值，目前的计算与以前的计算显着偏离了。 $ pp $ netrinos的更新的捕获率估计为$（4.47 \ pm 0.09）\ \ rm snu $和所有太阳中微子$（80 \ pm 21）\ \ rm snu $，含有中微子生存概率。根据XE的数量，太阳能$ pp $中微子可以以每天100的速度来测量，从而可以长时间实时监视它们。
Various large-scale experiments for double beta decay or dark matter are based on xenon. Current experiments are on the tonne scale but there are also ideas to aim for even larger sizes in the future. Here we study the potential of the isotope $^{131}$Xe to allow to make real-time measurements of solar $pp$ neutrinos, besides classical neutrino-electron scattering. Improved nuclear models are used to determine the cross-section of neutrinos on $^{131}$Xe. The present calculations deviate significantly from the previous ones due to updated estimates for the excited-state contributions. The updated capture-rate estimate for $pp$ neutrinos is $(4.47\pm 0.09)\ \rm SNU$ and for all solar neutrinos $(80\pm 21)\ \rm SNU$, with neutrino survival probabilities taken into account. Depending on the amount of Xe, solar $pp$ neutrinos might be measured with rates of 100 per day, thus allowing to monitor them in real time for a long period.
