The IBA-2 model of nuclear structure makes explicit predictions of isovector properties of collective states which have never before been tested. We have made the first measurements of separate neutron (Mn) and photon (Mp) matrix elements for the first 2+ and 3- states in 104, 106, 108, 110Pd by means of inelastic scattering of 180 MeV π+ and π-. It is found that the IBA-2 model with core polarization can explain the trend of the data for Mp and Mn/Mp, but only if its parameters are empirically adjusted.
