Transverse electron scattering form factors are calculated for 0 + ~ 2 + excitations in 160, Z4Mg and 4ยฐCa. The objective is to learn about the current flows associated with nuclear collective motions. The 2 + states considered in 160 and ~lCa are giant quadrupole vibrational excitations. In 24Mg, the 2 + state is the first excited rotational state. The form factors have been computed microscopically within the framework of the symplectic model and, in order to interpret the dynamical content of collective flows of the model, the results are compared with form factors calculated with collective models, for different collective flows. For the giant resonance state, we calculate the form factor for irrotational-flow vibrational motion and, for the rotational state, we use the rotor model with both rigid and irrotational current flows.
