Excited states with J(pi)=1( ) and 1(-) in Mg-26 were studied in a photon-scattering experiment using bremsstrahlung produced by an electron beam of 13.0 MeV kinetic energy provided by the superconducting electron linear accelerator ELBE. We determined the transition strengths from the 1( ) and 1(-) states to the ground state as well as to low-lying excited states. In addition, we observed a J=1 state at 11.154 MeV, above the neutron-separation energy of 11.093 MeV, and determined its partial gamma decay width for the first time.
