Resonance processes and nuclear excitation in muonic 205Tl

Abstract The L and K X-rays of muonic 205 Tl have been measured with an enriched (99.8 %) 205 Tl target. Two sets of resonance processes were included in the analysis, which led to satisfactory fits to the experimental spectra, and explain the anomalous intensity ratios between the fine structure components of the muonic L and K X-rays. At the same time, the M1 hyperfine structure constants, which show the finite distribution of the nuclear M1 moment, were determined. Also determined were the static nuclear E2 and M1 moments of the excited states.
