我们报道了一种测量亚稳态原子辐射中微子对辐射中宇称破坏效应的可能性，定向原子发射光子的非对称角分布和出现的圆极化。它们的观测，以及具有6个阈值的连续光子能谱，可以解释为是一个弱和量子电动力学过程的结合，发射γνIνjin终态。这种方法可能极大地有助于利用原子进行中微子质量谱，这是对中微子质量矩阵的系统确定。
We report on a possibility of measuring parity violating effects in radiative neutrino pair emission from metastable atoms; asymmetric angular distribution of emitted photons from oriented atoms and emergent circular polarization. Their observation, along with the continuous photon energy spectrum which has 6 thresholds, may be interpreted as events being a combined weak and QED process, emission ofγνiνjin the final state. The method may greatly help to perform neutrino mass spectroscopy using atoms, a systematic determination of the neutrino mass matrix.
