 note = {Pair-breaking effects induced by 3-MeV proton irradiations are examined in underdoped, optimally doped, and overdoped Ba 1−x  K x  Fe 2  As 2   single crystals in terms of suppression of the superconducting critical temperature T c  . The small residual resistivity (RR) in as-grown crystals shows the presence of negligible intrinsic scatterings, which makes this material a model system for studying the effect of artificially introduced scatterings. The RR and T c   change linearly with the proton dose. As in the case of proton irradiation in Co-doped BaFe 2  As 2  , we do not detect any low-temperature upturns in resistivity attributable to magnetic scattering or localization. Regardless of K doping levels, the critical value of the normalized scattering rate is much higher than that expected in s ±  -wave superconductors.},
