摘要
In the present paper we discuss in detail experiments of radiation damage and their effects on MgB2 properties (T-c, resistivity, critical field, gap), making constant reference to similar experiments performed in the seventies and eighties on A15 superconductors (Nb3Sn, V3Si). We will show that the overall behaviour of MgB2 and A15s is surprisingly similar, pointing out that similar mechanisms (smearing of density of states) plays a role at high radiation doses, whereas, at low radiation, two-band effects mainly determine the MgB2 behaviuor.
