Abstract: | Radioactive129mTe was implanted in 6 different transition metals (V, Fe, W, Au, Pt, Pb) and internal conversion electron spectra as well as Mössbauer spectra of the daughter nucleus129I were measured. A value (r
2)=+1.8(4)×10–2 fm2 (corresponding to R/R=+4.1(10)×10–4) was derived for the change of the mean square charge radius during the 27.8 keV transition in129I. The consequences of this measurement on the calibration constants of the Mössbauer isomer shifts of other isotopes of the 5sp elements are discussed. |
