Abstract
The nearest neighbour distribution (NND) and Δ3 statistics for the two-spin model are studied numerically. As one of the model parameters w increases from zero, the results show a standard Poisson–Wigner (GOE)–Poisson transition in the NND. In the integrable case w = 0, the NND of the model shows a remarkable deviation from the Poisson prediction, so gives a novel example of non-generic NND.
