Description
Two strong levels at 9.14 MeV in 52Cr and 56Fe have been excited by resonance fluorescence with linearly polarized, mono-energetic, gamma rays. Both decay to the ground state with essentially 100% probability. The azimuthal and polar asymmetry of the resonance-scattered radiation lead to unique spin-parity assignments of Jsup(π)=1+ and Jsup(π)=1- for the 52Cr and 56Fe levels, respectively. Resonance absorption measurements lead to absolute determination of the ground-state transition strengths: GAMMAsub(#betta#0)(52Cr)=2.68+-0.16 eV (B(M1)down=0.302+-0.018μsub(N)2) and GAMMAsub(#betta#0)(56Fe)=1.28+-0.17 eV.
