The specific heat of the recently discovered superconductor MgB2 has been m
easured at temperatures ranging from 4.5 to 80 K. The superconducting anoma
ly DeltaC at T-c is clearly observed. The total specific heat in the normal
state can be well fitted by electronic and phonon contributions. The Debye
temperature theta (D) is found to be 737 K, much larger than other interme
tallic superconductors. The normal-state electronic specific heat coefficie
nt gamma is found to be 2.48 +/- 0.5 mJ/mol (.) K-2 and DeltaC/gammaT(c) is
between 1.41 and 2.15.
