摘要：

From a finite size analysis we extract the structure factor S(p, N = infinity) of the one dimensional AFH-model in the groundstate: The 'gross' structure is well described by L (p)= -ln(1-pi(p)). The 'fine' structure which only contributes a few percent reveals a pronounced nonlinear behavior in L (p) with a maximum at p=0.20pi and a minimum at p=0.82pi.
