- Abstract
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 | f α β | ≤ 0. 8 6 × 1 0 − 7 (times the electron Bohr magneton) and the charge radius | r ̃ | < 4. 3 0 × 1 0 − 1 7 cm. For a nonvanishing millicharge () , the allowed bound is shown in the r ̃ 2 − plane.
