Abstract
Several states in $^{25}\mathrm{Mg}$ have been excited by 180\ifmmode^\circ\else\textdegree\fi{} inelastic electron scattering at bombarding energies of 39 and 56 MeV. A survey was made of the giant-resonance region comprising the upper half of the excitation range 0-27 MeV. In the lower half of this range, studied more intensively, the scattering has caused magnetic dipole transitions to states at 1.60, 5.77, 7.03, 7.81, 10.43, 11.37, and 11.76 MeV. Transition radii and ground-state transition widths are given for these levels. The results are discussed with respect to the collective rotational nature of the nucleus and to the existence of $T=\frac{3}{2}$ analog states.
