摘要
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 (E-gamma = 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 In-115(gamma, gamma')In-115m, are presented and analyzed in combination with data from tow-energy photon-scattering experiments (In-115(gamma, gamma')In-115). The quality of the results demonstrates the powerful capability of this new installation (C) 2001 Elsevier Science B.V. All rights reserved.
