Abstract
The two two-body operators representing the effect of far configurations on the contact hyperfine interaction in annl N n′s configuration are shown to reduce to one-body operators. In such a configuration the operator for the contact hyperfine field is (a nlSnl +an,ssn′s), where anl and an′s take the same values in all terms of the configuration. A discrepancy between expectation values of these two-body operators deduced from experiment and calculated values is explained.
