The Ca(e, e'x) reaction has been investigated for excitation energies between 8 and 26 MeV and momentum transfers from 0.25 to 0.66 fm ' at the continuous-wave electron accelerators MAMI at Mainz and S-DALINAC at Darmstadt. A multipole decomposition of the cross sections reveals strongly fragmented E2 (plus EO) strength around 14 and 17 MeV in contrast to all theoretical predictions. An-

With high-resolution inelastic electron scattering measurements on 46Ti and 48Ti the excitation mechanism of the transition into low lying J~ = 1 + states is investigated. The experimental evidence of considerable contribution of the orbital part of the M1 operator to the total transition strength is given by a model dependent analysis of form factors. The possibility of physical relationship to low lying J~=l + states in the rare earth nuclei is discussed in various models. Moreover E2 form factors and good candidates for M3 form factors are presented.
