Cryogenic scanning tunneling microscopy and magnetization measurements were used to study the superconducting properties of MgB2. The magnetization measurements show a sharp superconductor transition at T-c=39 K, in agreement with previous works. The tunneling spectra exhibit BCS-like gap structures, with gap parameters in the range of 5 to 7 meV, yielding a ratio of 2 Delta /k(B)T(c)similar to3-4. This suggests that MgB2 is a conventional BCS s-wave superconductor, either in the weak-coupling or in the intermediate-coupling' regime.
