A frequency average of the complex local-field correction function (LFCF), G(q, ¯ω), of electrons in Li metal has been semiempirically determined for 1.12kF1.6kF, the semiempirical ReG(q, ¯ω) exhibits a strong increase in values ranging from 1.2 to 2.4 in a manner which has not been predicted by any existing theory. The relation between G(q, 0) and the momentum distribution function n(k) is stressed to make contact with a most recently found anomalous behavior of n(k) in Li.
