Compton scattering from He 4 at the TUNL HIγ S facility

Published

Journal Article

© 2020 American Physical Society. Differential cross sections for elastic Compton scattering from He4 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. This experimental work is expected to strongly motivate the development of effective-field-theory calculations of Compton scattering from He4 to fully interpret the data.
