Calculation of the hyperfine fields in the noble-metal atoms

The hyperfine fields in the noble-metal atoms Cu, Ag, and Au have been calculated by means of a relativistic many-body perturbation-theory technique. The resulting hyperfine fields for these atoms were 256[plus minus]11, 531[plus minus]22, and 1997[plus minus]92 T, respectively, in good agreement wi...

Description
Summary:The hyperfine fields in the noble-metal atoms Cu, Ag, and Au have been calculated by means of a relativistic many-body perturbation-theory technique. The resulting hyperfine fields for these atoms were 256[plus minus]11, 531[plus minus]22, and 1997[plus minus]92 T, respectively, in good agreement with the experimental results of 259.95, 499.12, and 2085.1781 T. The reasons for the error bars in the theoretical results are discussed and are associated with the substantial sizes of the third- and higher-order correlation effects, which are found to be of great importance in these atoms. We will discuss the contributions to the total field from various one- and two-body interaction mechanisms and compare these contributions to those in related systems. Our results for the Cu and Au systems will also be compared with those available from other calculations reported in the literature.
