Abstract
A phenomenological expression for the high-temperature susceptibility is obtained by making a small modification of the binomial expansion of a power law. The equation contains the 'universal' exponent which pertains to the to the approach to Tc and an additional exponent to describe the power law in the high-temperature limit. The expression provides an alternative to the method of Pade approximants for analysing high-temperature series expansions in powers of inverse temperature. The conclusions of M. Fahnle and J. Souletie (1984) that there is interesting physics in the high-temperature power laws is supported.Keywords
