摘要
The isotope shifts (IS) of Bi-202,Bi-203,Bi-204 have been measured on the 306.7 nm line using an extremely sensitive gas cell technique of laser spectroscopy. A King plot analysis of this data with other IS measurements in neighbouring isotope chains reveals that the known scaling behaviour of relative changes in mean square nuclear charge radius is only strictly ovserved above the Z = 82 shell closure.
