Title: Compton scattering from He 4 at the TUNL HI γ S facility

Abstract

Differential cross sections for elastic Compton scattering from 4He have been measured with high statistical precision at the High Intensity γ-ray Source at laboratory scattering angles of 55°, 90°, and 125° using a quasi-monoenergetic photon beam with a weighted mean energy value of 81.3 MeV. The results are compared to previous measurements and similar fore-aft asymmetry in the angular distribution of the differential cross sections is observed. Lastly, this experimental work is expected to strongly motivate the development of effective-field-theory calculations of Compton scattering from 4He to fully interpret the data.
