We have computed many terms of the power series expansion of (2.7) about
s=0 with b=1 and subject to (2.8). Substitution of the first seven into
Comparison with the analogous expansion of (1.3a) (see e.g. ) shows that
, which in qualitative terms says that
very small spacings between consecutive eigenvalues will most likely be
nearest neighbour spacings (the factor of 1/2 accounts for the fact that the
nearest neighbour occurs with equal probability to the left or the right).
