| الوصف: | International audience ; The dipole strength of the N = 28 closed-shell nuclide 54 Fe was studied in photon-scattering experiments using bremsstrahlung produced with electron beams of kinetic energies of 7.5 and 13.9 MeV at the γ ELBE facility as well as using quasimonoenergetic and linearly polarized photon beams of 26 different energies within the range from 5.5 to 11.4 MeV at the HIγ S facility. About 100 J = 1 states were newly identified, out of them 19 with 1 + and 30 with 1 − assignments. The quasicontinuum of unresolved transitions was included in the analysis of the spectra and the intensities of branching transitions were estimated on the basis of simulations of statistical γ-ray cascades. As a result, the photoabsorption cross section up to the neutron-separation energy was determined and compared with predictions of the statistical reaction model. The experimental M1 strengths from resolved 1 + states are compared with results of large-scale shell-model calculations. |
