Description

We discuss a new method for measuring the critical exponent γ for the partition function of the Bosonic string. The statistics seems very good and the fit to γ consists with the assumed asymptotic form for the partition function for dimensions d=1-6. The results are in agreement with analytical results when the target space dimension is d=0, but disagree when d=1. We conjecture that this is due to the appearance of logarithmic corrections to the asymptotic form of the partition function. These corrections might persist for d>1 and might render a determination of γ quite difficult. (orig.)
