在考虑宏观靶系统相干效应的情况下，研究了原子去激发过程中的中微子对辐射。在制备相干初态以提高速率的过程中，在宏观靶上印记了一个空间位相因子。结果表明，这一初始空间位相改变了辐射中微子对发射的运动学。我们研究了初始空间位相对这一过程光子谱的影响。结果表明，初始空间位相给我们在探索中微子物理方面提供了显着的改进，例如狄拉克-马约拉纳区分和宇宙中微子背景。
We study radiative neutrino pair emission in deexcitation process of atoms taking into account coherence effect in a macroscopic target system. In the course of preparing the coherent initial state to enhance the rate, a spatial phase factor is imprinted in the macroscopic target. It is shown that this initial spatial phase changes the kinematics of the radiative neutrino pair emission. We investigate effects of the initial spatial phase in the photon spectrum of the process. It turns out that the initial spatial phase provides us significant improvements in exploring neutrino physics such as the Dirac-Majorana distinction and the cosmic neutrino background.
