Query: Spacings between phase shifts in a simple scattering problem   We prove a scattering theoretical version of the Berry-Tabor conjecture: for
an almost every surface in a class of cylindrical surfaces of revolution, the
large energy limit of the pair correlation measure of the quantum phase shifts
is Poisson, that is, it is given by the uniform measure.
