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.

The giant-resonance region in 40 Ca and 48 Ca has been studied using the reactions 48 Ca(p,pЈn 0 ) 47 Ca, 40 Ca(p,pЈp 0 ) 39 K, and 40 Ca(p,pЈ␣ 0 ) 36 Ar for an incident proton energy E p ϭ100 MeV. Knockout cross sections for these reactions were calculated within the distorted wave impulse approximation formalism using parameters fixed from previous investigations. The results quantitatively account for the data at higher excitation energies while the knockout contributions underneath the main resonance strength are small.
