We derive low-temperature expansions of the internal energy, the specific heat and so on for the antiferromagnetic Ising model on a triangular lattice by using the expression obtained by Stephenson. We propose to use ∂T=exp (2βJ) as the reduced temperature variable near the critical temperature. We then conclude the values of the critical exponents α, ν, γ, ∂ and ∂ as α=0, ν=1, γ=3/2, ∂=7 and ∂ =7/4.
