Variations of nuclear charge radii in mercury isotopes withA=198, 199, 200, 201, 202, and 204from x-ray isotope shifts

Abstract

The isotope shifts of atomic $K$ x rays were measured for pairs of the six mercury isotopes with $A=198, 199, 200, 201, 202, \mathrm{and} 204$, using a curved crystal spectrometer. The changes of the nuclear charge radii were derived in terms of $\delta 〈r^2〉$ and $\delta R_k$ and compared with optical and muonic isotope shift data. From our results, a renormalization of the optical data was obtained.
