Inelastic electron scattering from 25Mg

The excited states of 25Mg have been studied by inelastic electron scattering in the momentum transfer range 0.3 to 1.15 fm-1. The reduced transition probabilities and transition radii were measured for seven levels below 4.1 MeV excitation energy and the transition probabilities are shown to be more precise than existing measurements. A search for the hexadecupole strength to the 11/2+ levels in the vicinity of 5-6 MeV excitation energy was also carried out. The applicability of an extended Nilsson-model description for the ground-state band of 25Mg was also investigated by comparison with the known electromagnetic strengths, and, more crucially, by comparison with the measured form factors.
