Transition Charge Densities of the21+and22+States inPd106andCd114

We have obtained inelastic electron-scattering $2_1^{+}$ and $2_2^{+}$ form factors in ${}_{}{}^{106}{}_{}{}^{}\mathrm{Pd}$ and ${}_{}{}^{114}{}_{}{}^{}\mathrm{Cd}$ in the momentum-transfer range between 0.6 and 1.8 ${\mathrm{fm}}^{-1\mathrm{}}$. The transition charge densities of the $2_1^{+}$ and $2_2^{+}$ levels were extracted from the experimental form factors by assuming a phonon model in which the one- and two-phonon states are mixed. The wave functions (transition charge densities) obtained have been found to describe reasonably the measured $2_1^{+}$ quadrupole moments and the radiative transition rates of the crossover and cascade $\gamma$ rays.
