Abstract

We investigate the ^kz dispersion in the hole Fermi surfaces (FSs) and the superconducting (SC) gaps of BaFe ₂(As _0.65P _0.35) ₂ by employing bulk-sensitive angle-resolved photoemission spectroscopy (ARPES) with low energy photons. We find that this material exhibits a comparable magnitude of SC gaps for three-hole FSs at ^kz∼π. The comparable magnitude of the SC gap is observed also at ^kz∼ 0. Since each FS sheet has a distinct orbital character, these observations are an indication of the orbital-independent SC gaps in the hole FSs.
