Experimental and calculated radionuclide production by photonuclear reactions using bremsstrahlung photons produced by 150 MeV electrons

摘要

The authors have developed an experimental apparatus to study radionuclide production by photonuclear reactions. A nearly neutron free bremsstrahlung beam was created by incident electron interactions with a tantalum radiator. They studied photonuclear reactions in different samples, including the elements Be, Na, Si, Cl, and Ge. Decay gamma rays from radionuclides having half lives > 2 min were analysed. Using the PICA code, the authors calculated the yield of radionuclides for silicon. They have observed and assigned a new gamma ray transition, of E(y) = 1153 keV, to the decay of 6.6 min 29-Al.
