One-phonon 2(1,ms)(+) mixed-symmetry state of Sm-148 observed in nuclear resonance fluorescence: To search for the 2+1,ms state of 148Sm, we studied the 148Sm(γ,γ′) photon scattering reaction at the Stuttgart Dynamitron accelerator using bremsstrahlung with an endpoint energy of 3.2 MeV. Nuclear resonance fluorescence from eleven excited states, including three 2+ states, between 1.4 and 3.1 MeV has been observed. The data allow the identification of the 2+5 state at 2146 keV as the 2+1,ms state of 148Sm.
