Abstract

This is the first of two papers discussing a new signature of quadrupole mixed-symmetry states in the vibrational nuclei 92,94Zr and 94Mo based on proton and neutron transition densities derived from the comparison of inelastic electron and proton scattering experiments. Results of the (e,e′) and (p,p′) experiments on these nuclei as well as (p,p′) data for other potential cases 96Mo and 70Zn are presented. Spin and parity quantum numbers of excited states are assigned based on angular distributions from the proton scattering data in comparison to calculations employing form factors from the collective model in distorted-wave Born approximation. Possible candidates of one-phonon fully symmetric and mixed-symmetry states as well as members of two-phonon multiplets are identified.
