Dipole strength in 120Sn up to 9.1 MeV from resonant photon scattering * — •Banu Özel1,2, Joachim Enders1, Yaroslav Kalmykov1, Peter von Neumann-Cosel1, Achim Richter1, Deniz Savran1, and Andreas Zilges1 — 1Institut für Kernphysik, Technische Universität Darmstadt, 64289 Darmstadt, Germany — 2Science and Art Faculty, Cukurova University, 01330 Adana, Turkey
The 120Sn(γ,γ′) reaction was studied at 7.5 and 9.1 MeV endpoint energies of the incident bremsstrahlung spectrum at the superconducting Darmstadt electron linear accelerator S-DALINAC. Dipole transition strength distributions are extracted for 120Sn and compared with existing data for 120Sn [1], 116,124Sn [2] and 130,132Sn [3]. Furthermore a fluctuation analysis is applied to the photon scattering spectra to estimate the amount of the unresolved strength hidden in background due to the fragmentation of the strength.
