Abstract

Isotope shifts in dielectronic recombination spectra were studied for Li-like ANd57+ ions with A=142 and A=150. From the displacement of resonance positions energy shifts dE142?150(2s-2p1/2)=40.2(3)(6)??meV [(stat)(sys)] and dE142?150(2s-2p3/2)=42.3(12)(20)??meV of 2s-2pjtransitions were deduced. An evaluation of these values within a full QED treatment yields a change in the mean-square charge radius of 142?150d?r2?=-1.36(1)(3)??fm2. The approach is conceptually new and combines the advantage of a simple atomic structure with high sensitivity to nuclear size.
