On the calculation of field isotope shifts for optical spectral lines

Abstract

An additional factor of (n/N)3 has to be included in the usual procedure for deducing the change in mean square nuclear charge radii from optical field isotope shift measurements, n and N being the principal and the relativistic quantum number of the s-electron respectively. This correction amounts to about 8 % for heavy atoms as for example Hg leading to better agreement between results from optical field isotope shift measurements and from electronic and muonic X-ray data.

Additional information

In view of the high accuracy of recent optical field shift measurements the correction proposed in this short note should also be of importance for other heavy atoms and may contribute to a better agreement between data for the change in mean square nuclear radii from different experimental methods.
