Abstract :
At the Stuttgart 4.3 MV DYNAMITRON accelerator a new bremsstrahlung irradiation facility was installed for photoactivation experiments to complement the well-established arrangement for systematic photon-scattering studies taking advantage of the high photon fluxes achievable at this high-current accelerator. The population or depopulation of isomeric states in low-energy photon-induced reactions (Eγ=0.5–4.0 MeV) can be studied with sensitivities far beyond previous limits. The setup of this facility, its performance, and the absolute calibrations are described in detail. First exemplary results for a test case, the reaction 115In (γ,γ′) 115m In, are presented and analyzed in combination with data from low-energy photon-scattering experiments (115In (γ,γ′) 115 In). The quality of the results demonstrates the powerful capability of this new installation.
