Transverse electron scattering form factors have been measured for isoscalar transitions to T=0 levels in ${}_{}{}^{24}{}_{}{}^{}\mathrm{Mg}$ at 1.37 MeV ($J^{\pi }$${=2\mathrm{}}^{+}$), 5.24 MeV ($3^{+}$), 6.01 MeV ($4^{+}$), and for the unresolved T=0 doublet at 4.12 MeV ($4^{+}$) and 4.24 MeV ($2^{+}$). Because of the large longitudinal form factors for these transitions, sometimes exceeding the transverse form factor by more than a factor of ${10}^4$, it was necessary to observe electrons scattered at 180° so that longitudinal scattering was minimized. Several incident energies from 80.1 to 200.5 MeV were used to span effective momentum transfers from 0.84 to 2.07 ${\mathrm{fm}}^{\mathrm{-}1}$. Results are compared with predictions calculated using Dirac wave functions for the nuclear bound states in a Woods-Saxon potential well.
