High-temperature expansions of the susceptibility and specific heat are calculated to the eighth and ninth orders, respectively, in the reciprocal temperature for the one-dimensional ferromagnetic Ising model with interaction that decreases inversely as the square of the distance between the lattice sites. An analysis is performed of the expansion of the susceptibility that indicates that at the critical point its logarithm diverges in accordance with a power law exponent. This estimate is close to the value obtained by the renormalization-group method and is the first numerical confirmation of the predictions of the renormalization-group approach for systems with long-range interaction.
