Generalized oscillator strengths for the Na 3s-3p transition have been investigated using the spin-polarized technique of the random phase approximation with exchange (RPAE) and the Hartree-Fock approximation, focusing our attention on the position of the minimum. Intershell correlations are found to influence the position of the minimum significantly, but hardly that of the maximum. The RPAE calculation predicts the positions of the minimum and maximum at momentum transfer, K values of 1.258 and 1.61 a.u., respectively. The former value is within the range of values K=1.0–1.67 a.u. extracted by us from experimental measurements. We recommend a careful experimental search for the position of the minimum around the predicted value for confirmation.
