Changes of mean-square nuclear charge radii from isotope shifts of electronic K α X-rays

Abstract

Experimental results on K α x-ray isotope shifts are summarized. The δ 〈 r 2 〉 values of the nuclear charge distribution, as derived from the data, are presented. A combination of x-ray and optical isotope shifts, in some cases, yields an improved accuracy for δ 〈 r 2 〉. The mass-shift corrections to the x-ray isotope shifts are presented.
