High Resolution Measurement of the ^16O(γ,pn)^14N_0,1,2... Reaction
Abstract
Results of the ^16O(γ,pn)^14N_0,1,2... measurement will be presented. This measurement used the photon tagging facility located at the University of Saskatchewan Accelerator Laboratory. The tagged photon energy range was from 100 to 140 MeV. Events in which the photon interacted within the nucleus resulting in the simultaneous emission of a proton and a neutron were recorded. The protons were detected using high resolution CsI(Tl) detectors while the neutron's energy was determined by a time-of-flight measurement. In order to reconstruct the residual states in ^14N a net missing energy resolution of approximately 2 MeV FWHM was desired. By resolving the residual states and using the known spin, parity and isospin, information about the quantum numbers of the two nucleon photoabsortion mechanism can be extracted within the frame work of a spectator model for the recoil ^14N nucleus.
