Abstract
We present a detailed analysis of the nearest-neighbour spacing distri bution (NNSD) for random matrices on which the non-zero elements are c onfined to a band around the diagonal. The vanishing of the remaining elements induces non-analytic (logarithmic) behaviour for the NNSD at very small spacings. A conjecture for the precise behaviour of these l ogarithmic terms is presented and supported by extensive numerical com putations.
