A measurement of charge transition radii differences of 2+ one-phonon states of vibrational nuclei deduced
from electron scattering at low momentum transfer provides information about the different interferences of the
dominant valence shell components [1]. It is demonstrated in a case of 92Zr that the method based in model
independent PWBA analysis is applicable in heavy nuclei and furthermore permits a precise determination of
the B(E2) strength of the 2+ mixed-symmetry states. The results will be also compared to experimental results
extracted using the QPM and to the result extracted using a (n,n′ γ)experiment.
