地中微子与地球内部结构
Geoneutrinos and the Earth inner parts structure
摘要：
讨论了地中微子登记与地球理论检验之间的联系。比较了标准的岩石圈板块理论和氢化物地球假说。最后一个假设增加了额外的中微子源$-$行星核心，其中初始地球成分是保守的。大体积闪烁探测器应该安装在高加索的巴克桑中微子天文台INR RAS。探测器将记录所有可能的中微子通量，但主要是地球中微子。因此，放置在地球表面许多地点的探测器（或探测器网）可以测量来自$^{238}$ U和$^{232}$ Th的所有放射性，因为它们的中微子能量超过了逆β衰变反应的阈值。通过这种方法，有可能了解除了地壳和地幔之外，地球上是否还有更多的中微子源。
英文摘要：
The connection between geoneutrino registration and the Earth theory test is discussed. We compare standard theory of lithosphere plates and hypothesis of hydride Earth. Last hypothesis adds additional neutrino source $-$ planet core in which the initial Earth composition is conserved. Large volume scintillation detector is supposed to install at Baksan neutrino observatory INR RAS at Caucasus. The detector will register all possible neutrino fluxes, but mainly geo-neutrinos. So kind a detector (or detector net) placed in a number of sites on the Earth surface can measure all radioactivity from $^{238}$U and $^{232}$Th, because their neutrino energy exceeds the inverse beta-decay reaction threshold. By this way it will it possible to understand if there are any more neutrino sources in the Earth other than the crust and mantle.
