Abstract: | Radioactive83Rb was implanted in 6 different cubic metals (Al, W, Au, Ir, Pt, Pb) and both internal conversion electron spectra and Mössbauer spectra of the daughter nucleus83Kr were measured. A value (r
2)=+5.1(9)×10–3 fm2 (corresponding to R/R=+1.6(3)×10–4) was derived for the change of the mean square charge radius during the 9.40 keV transition in83Kr. The systematics of the isomer shifts of krypton and other sp-elements substitutionally dissolved in metals are discussed. |
