Abstract
Tunnel conductances of superconducting polycrystalline MgB2 samples were measured by the break-junction technique. Three main gap-like peculiarities are observed, while other ones scatter from sample to sample. These results correlate with heat capacity measurements, an analysis which shows a wide range of energy gaps involved.
