Abstract

The transition charge and current densities for the lowest E5 proton particle-hole excitation in ⁸⁹Y (0.909 MeV) and ⁹⁰Zr (2.319 MeV) have been extracted from electron scattering data. These excitations are dominated by the π(1 g_{9 2}, 2 p^-1 _{9 2}) configuration. The transition densities indicate the importance of configuration mixing in the ground state of ⁹⁰Zr. Single-particle predictions do not reproduce the shape of the empirical densities indicating the need for a surface peaked core polarization correction in both the charge and current densities.
