In this paper, we consider the effects of bound atomic electrons scattered by solar neutrinos due to the electromagnetic properties of neutrinos. This necessitates considering the recoil of atomic nucleus, which should be considered in the momentum conservation, but the effect to the energy conservation is negligible. This effect changes the kinematic behavior of the scattered electron compared to that scattered on free electrons. We apply this effect to the recent XENON1T data, but the bounds obtained from this are not very restrictive. We obtained the bounds: the (transition) magnetic moment |fαβ|≤ 0.86 × 10−7 (times the electron Bohr magneton) and the charge radius |r̃| < 4.30 × 10−17 cm. For a nonvanishing millicharge (𝜀), the allowed bound is shown in the r̃2 − 𝜀 plane.

原子中束缚电子散射的中微子电磁特性

在本文中，我们考虑了由于中微子的电磁特性而被太阳中微子散射的束缚原子电子的影响。这就需要考虑原子核的反冲，在动量守恒中应该考虑，但对能量守恒的影响可以忽略不计。与散射在自由电子上的相比，这种效应改变了散射电子的运动学行为。我们将此效果应用于最近的 XENON1T 数据，但从中获得的界限不是很严格。我们得到了界限：（过渡）磁矩|Fαβ|≤ 0.86 × 10-7（乘以电子玻尔磁子）和电荷半径|r̃| < 4.30 × 10-17厘米。对于不消失的毫电荷(𝜀)，允许的界限显示在r̃2 - 𝜀飞机。
