Abstrakt: A least-squares method for the combined analysis of two types of experimental data on nuclear charge radii has been developed. The data types are (1) radii measured from electron scattering and muonic atom spectra and (2) radii changes determined from optical isotope shifts. The nuclear charge radii systematics thus derived exhibit the following essential features: (i) the independently measured radii for the individual isotopes of an element are additionally constrained by the high accuracy of the extended isotopic chain of radii change values, (ii) unknown nuclear radii values are predicted for many isotopes of that element, and (iii) the accuracy of the fitted nuclear radii values is higher than that of the original independently measured values. The table presents a new set of nuclear radii systematics for 42 elements from 11Na to 95Am. These are elements for which there exist both types of experimental data. The range of isotopic numbers covered is determined by the range of the second type of data available.Copyright 1994, 1999 Academic Press, Inc.
