A simple analytic expression for the hyperfine contact density of an ion immersed in an electron gas is derived by an augmented WKB method. This expression, which is independent of the details of the screened ionic potential, agrees with numerical calculations by Micah, Stocks and Young (see abstr. A4594 of 1970) in the high density limit, and may be used as a rough estimate of the contact density in real metals.
