Abstract
With high-resolution inelastic electron scattering measurements on46Ti and48Ti the excitation mechanism of the transition into low lying Jπ=1+ states is investigated. The experimental evidence of considerable contribution of the orbital part of theM1 operator to the total transition strength is given by a model dependent analysis of form factors. The possibility of physical relationship to low lying Jπ=1+ states in the rare earth nuclei is discussed in various models. MoreoverE2 form factors and good candidates forM3 form factors are presented.
