- Point contact spectroscopy results are presented on the electron underdoped $Ba(Fe_{0.96}Co_{0.04})_2As_2$ single crystals. Two superconducting energy gaps with coupling values 2 $Δ_1$ ∿ $kT_{c}$ ≈ 2.55 and 2 $Δ_2$ ∿ $kT_{c}$ ≈ 11 at $T_{c}$ = 15.5 K have been observed in the point contact spectra. The temperature dependence of the normal state background of the point contact spectra observed between $T_{c}$ and $T_{N}$ indicates antiferromagnetic origin of the V-shaped minimum at zero bias.
