Singular statistics revised — •Timur Tudorovskiy, Ulrich Kuhl, and Hans-Jürgen Stöckmann — Fachbereich Physik, Renthof 5, D-35032 Philipps-Universität Marburg

We analyze the “singular statistics” of pseudointegrable Šeba billiards and show that taking into account growing number of resonances one observes the transition from “semi-Poissonian”-like statistics to Poissonian. This observation is in agreement with an argument that a classical particle does not feel a point perturbation. However, our findings contradict results reported earlier (P. Šeba, Phys. Rev. Lett. 64, 1855 (1990)).
