In combination with London penetration depth and resistivity measurements, the irradiation was particularly useful as a phase - sensitive probe of the superconducting order parameter in iron - based superconductors lending strongest support to sign - changing $s_{\\pm}$ pairing. Here we review the key results on the effect of electron irradiation in iron-based superconductors.","authors_text":"Kyuil Cho, M. A. Tanatar, M. Konczykowski, R. Prozorov, S.
