The distribution of magnetic dipole transition strength in Zr90 has been measured at excitations between 8.1 and 10.5 MeV with highly polarized tagged photons. A total M1 strength of Jg02(M1)/ =37.7-4.0+5.1 eV was found to be broadly distributed throughout the region. This strength can account for the giant M1 resonance predicted in Zr90. A substantial amount of E1 transition strength was also identified. This E1 strength has important implications for the interpretation of forward-angle (p,p) scattering and its use in identifying M1 transitions in heavier nuclei.
