Author(s): K. Nakayama, T. Sato, P. Richard, Y.-M. Xu, T. Kawahara, K. Umezawa, T. Qian, M. Neupane, G. F. Chen, H. Ding, and T. Takahashi We have performed angle-resolved photoemission spectroscopy on the overdoped Ba_{0.3} K_{0.7} Fe_{2} As_{2} superconductor (T_{c} =22 K). We demonstrate that the superconducting (SC) gap on each Fermi surface (FS) is nearly isotropic whereas the gap value varies from 4.4 to 7.9 meV on different FS... [Phys. Rev.
