摘要：

The first fully on-line isotope shift measurement of a radioactive refractory element is reported. Collinear laser-induced fluorescence measurements were made on the radioactive isotopes Hf-170,Hf-172,Hf-173,Hf-174 produced with a flux of 2-3 x 10(3) ions per second from an ion-guide fed isotope separator. The method may be applied to all elements and isomers with lifetimes as short as I ms. The systematics of the new charge radii measurements are well reproduced by theory, with the maximum deformation in the chain occurring significantly below the midshell.
