Abstract

The electron density at the gold nuclei in metallic gold and in the cubic intermetallic compounds CsAu, RbAu, AuMg, AuZn, AuCd, AuSc, AuAl2, AuGa2, AuIn2, AuSn2 and AuSb2 have been calculated using the Wien97 computer code. The electron densities thus obtained and the experimental values of the isomer shifts define a linear correlation spanning nearly the whole range of isomer shifts observed for the 77 keV transition of 197Au. From the slope of this correlation one obtains Δ<r 2> = (4.6 ± 0.2) · 10−3 fm2 for the change of the mean square nuclear charge radius accompanying 77 keV transition in 197Au.
