A formula, which is a useful improvement over existing ones, has been obtained to calculate the generalized oscillator strengths (GOS's) for the discrete transitions of both open-shell and closed-shell atoms. We illustrate our formula by calculating the GOS for the oxygen 2p{sup 4}({sup 3}P)-2p{sup 3}({sup 4}S)3s({sup 3}S) transition and obtain overall good agreement with the experimental data. Our calculated GOS reveals a minimum at around the momentum transfer, K=1.26 a.u. We recommend a careful experimental search for the position of the minimum around the predicted value for confirmation.
