Abstract: (Elsevier)
By means of an MC simulation of lattices of size 4 3 to 8 3 , we study the distribution of the complex zeroes closest to the real β axis of the d = 3 Ising model. We observe they do scale and we measure in this way ν and A + / A - . We obtain the prediction A + / A - = 0.45±0.07.
