Inelastic neutron and x-ray scattering as probes of the sign structure of the Fe-pnictide superconducting gap

T. A. Maier, S. Graser, P. J. Hirschfeld +1

Neutron spin-flip scattering observations of a resonance in the superconducting state is often taken as evidence of an unconventional superconducting state in which the gap changes…
