Abstract
Recent results giving both the asymptotic behavior and the explicit values of the leading-order perturbation-expansion terms in fixed dimension for the coefficients of the Callan-Symanzik equation are analyzed by the the Borel-Leroy, Padé-approximant method for the -component model. Estimates of the critical exponents for these models are obtained for in three dimensions with a typical accuracy of a few one thousandths. In two dimensions less accurate results are obtained.
