Abstract
The and models for the superconducting state are subject of intense studies regarding Fe-based superconductors. Depending on the parameters, disorder may leave intact or suppress in these models. Here we study the special case of disorder with equal values of intra- and interband impurity potentials in the two-band and models. We show that this case can be considered as an isolated point and there has maximal damping for a wide range of parameters.
