Photodisintegration cross section of the reaction 4He(γ,n)3He at the giant dipole resonance peak

Published

Journal Article

The photodisintegration cross section of 4He into a neutron and helion was measured at incident photon energies of 27.0, 27.5, and 28.0 MeV. A high-pressure 4He-Xe gas scintillator served as target and detector while a pure Xe gas scintillator was used for background measurements. A NaI detector in combination with the standard HIγS scintillator paddle system was employed for absolute photon-flux determination. Our data are in good agreement with the theoretical prediction of the Trento group and the recent data of Nilsson but deviate considerably from the high-precision data of Shima. © 2012 American Physical Society.
