Investigation of the odd mass Tl isotopes in resonant photon scattering experiments * — •Nadia Benouaret, Christopher Romig, Jacob Beller, Markus Zweidinger, Marcus Scheck, and Norbert Pietralla — Institut für Kernphysik, Technische Universität Darmstadt Schlossgartenstraße 9, 64289 Darmstadt, Deutschland
First nuclear resonance fluorescence (NRF) experiments have been performed on the odd mass isotopes 203,205Tl using a bremsstrahlung photon beam at an endpoint energy of 7.5 MeV at the S-DALINAC facility at TU Darmstadt. The measurements were complemented by additional experiments carried out at the High Intensity γ-ray Source HIγS at Duke University, NC, USA, with a linearly polarised quasi-mono-energetic photon beam. New photo-excited states of 203,205Tl isotopes have been identified. The ground state transition widths and the reduced transition probabilities of 205Tl have been extracted from the corresponding measured energy spectra of the scattered photons. The results on 205Tl will be presented.
