The observation of Fermi-surface(FS)-dependent nodeless superconducting gaps suggested that inter-FS interactions may play a crucial role in superconducting pairing. In the optimally hole-doped Ba$_{0.6}$K$_{0.4}$Fe$_2$As$_2$, the pairing strength is enhanced simultaneously (2$\\Delta$/Tc$\\sim$7) on the nearly nested FS pockets, i.e. the inner holelike ($\\alpha$) FS and the two hybridized electronlike FSs, while the pairing remains w","authors_text":"G.
