Comment on “Breakdown of the tensor component in the Skyrme energy density functional”

In a recent paper [Phys. Rev. C 101, 014305 (2020)], Dong and Shang claim that the Skyrme original tensor interaction is invalid. Their conclusion is based on the misconception that the Fourier transform of tensor interaction is difficult or even impossible so that the Skrme-type tensor interaction was introduced in an unreasonable way. We disagree with their claim. In this Comment, we show that one can easily get the Skyrme force in momentum space by Fourier transformation if one starts from a general central, spin-orbit, or tensor interaction with a radial dependence.
