Abstract

The far-infrared conductivity of MgB₂ that encompass a frequency range spanning excitations across the fundamental superconducting energy gap was measured. It was shown that THz conductivity of MgB₂ in the vicinity of its superconducting gap 2Δ₀ exhibits a BCS-like shape but an unusually small gap ratio.
