Highly precise data on the magnetic dipole strength distributions from the Darmstadt electron linear accelerator for the nuclei ${}^{50}\mathrm{T}\mathrm{i}$, ${}^{52}\mathrm{C}\mathrm{r}$, and ${}^{54}\mathrm{F}\mathrm{e}$ are dominated by isovector Gamow-Teller-like contributions and can therefore be translated into inelastic total and differential neutral-current neutrino-nucleus cross sections at supernova neutrino energies. The results agree well with large-scale shell-model calculations, validating this model.
