The Resonance Process and the Intensity Anomaly in Muonic 127I

Abstract The muonic N, M, L and K X-rays of 127 I have been measured and analyzed. A resonance process involving the muonic 2p levels and the nuclear ground and first excited states was included in the analysis. A satisfactory fit to the experimental spectra was achieved, at the same time, the parameters of the Fermi charge distribution, the M1 and the E2 hyperfine structure constants and the M1 and the E2 transition moments were determined. The M1 hyperfine structure constants and the M1 transition moment showed the effects of the finite distribution of the static and the transition M1 moments, while the E2 hyperfine structure constants offered an independent determination of the electric quadrupole moment.
