In order to spectroscopically probe the s uperconducting energy gap of potassium-doped Ba122 i ron pnictides, in particular Ba_(1-x)K_xFe₂As₂ where x = 0.33 (under-doped regime), we have performed four-wire conductance measurements from T = 2K to 52K. We report evidence for multi-gap features with gaps corresponding to directional tunneling through the ab - axes of this iron pnictide. The multi-gap features a predominant result o f tunneling across the ab - plane with gaps of Δ₁ = 2-4 meV and Δ₂ = 9-11 meV. These gap values are temperature dependent.
