Abstract
Non-magnetic impurities can lift the accidental degeneracy of unconventional pairing states, such as the -wave state recently proposed for SrRuO. This type of effect would lead to a superconducting double transition upon impurity doping. In a model calculation it is shown how this behavior depends on material parameters and how it could be detected.
