Abstract

Inelastic neutron scattering provides a probe for studying the spin and momentum structure of the superconducting gap. Here, using a two-orbital model for the Fe-pnictide superconductors and a random-phase approximation–BCS approximation for the dynamic spin susceptibility, we explore the scattering response for various gaps that have been proposed.
