Точное измерение комптоновского рассеяния в области 5 ГэВ

Ребята из CEBAF (a.k.a. Jefferson Lab) сподобились:

High Precision Measurement of Compton Scattering in the 5 GeV region: https://arxiv.org/abs/1903.05529

The cross section of atomic electron Compton scattering γ+e→γ′+e′ was measured in the 4.40--5.475 GeV photon beam energy region by the {\em PrimEx} collaboration at Jefferson Lab with an accuracy of 2\% and less. The results are consistent with theoretical predictions that include next-to-leading order radiative corrections. The measurements provide the first high precision test of this elementary QED process at beam energies greater than 0.1 GeV.
