Abstract
We derive a semi-classical Wigner-Kirkwood expansion (\(\hbar\) expansion) of the linear response functions. We find that the semi-classical results compare very well to the quantum mechanical calculations. We apply our formalism to the spin-isospin responses and show that surface-peaked \({{\hbar }^{2}}\) corrections considerably decrease the ratio longitudinal/transverse as obtained through the Los Alamos \((\vec{p},{{\vec{p}}^{1}})\) experiment.
