Abstract

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 (M_n) and photon (M_p) matrix elements for the first 2⁺ and 3^- states in ^{104, 106, 108, 110}Pd 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 M_p and M_n/M_p, but only if its parameters are empirically adjusted.
