Add to ORKGWe report specific heat measurements on neutron-irradiated MgB2 samples, for which the criticaltemperature is lowered to 8.7 K, but the superconducting transition remains extremely sharp, indicative ofa defect structure extremely homogeneous. Our results evidence the presence of two superconducting gapsin the temperature range above 21 K, while single-gap superconductivity is well established as a bulkproperty, not associated with local disorder fluctuations, when Tc decreases to 11 K
