Abstract
Extrapolations of high-field and high-temperature series expansions have been used to construct numerical approximations to the density of zeros on the Lee-Yang circle for the Ising ferromagnets on a two-dimensional square and a three-dimensional diamond lattice. For temperatures above the critical temperature the density is zero for and then varies as , with for the square and diamond lattices, respectively.
