Abstract
The multifractal spectrum f(alpha) characterizing the scaling properties of the growth probability on the boundary
of radial diffusion-limited aggregates is known to exhibit strong finite size effects. We demonstrate that
there exists a correlation between these finite size effects and those present in measurements of the angular
width of the fjords which lie between the principal cluster arms. We subsequently conclude that it is the
evolution in the global structure of the clusters which is responsible for the slow convergence in f(alpha) and
discuss how this global structure induces a phase transition in f(alpha).
