Sugai, Y. Mizuno, R. Watanabe, T. Kawaguchi, K. Takenaka, H. Ikuta, K. Kiho, M. Nakajima, C. Lee, A. Iyo, H. Eisaki, S. Uchida] The spin density wave (SDW) transition in BaFe2As2 and the superconducting transition in BaFe1.84Co0.16As2 were investigated by Raman scattering. The symmetries of the nodal SDW gap at 400cm−1 and the superconducting gap at 75cm−1 are bothB 2g. The superconducting coherent peak energy is smaller than the gap energy of the hole pocket, indicating that the peak is the resonant peak in the S ± superconductor. The superconducting symmetry is given by B 2g in the orbital combination and A 1g (S ±) in the momentum space. The exchange interaction energies are estimated from the two-magnon peak.
