  For the paradigmatic three-disk scattering system, we confirm a recent
conjecture for open chaotic systems, which claims that resonance states are
composed of two factors. In particular, we demonstrate that one factor is given
by universal exponentially distributed intensity fluctuations. The other
factor, supposed to be a classical density depending on the lifetime of the
resonance state, is found to be very well described by a classical
construction. Furthermore, ray-segment scars, recently observed in dielectric
cavities, dominate every resonance state at small wavelengths also in the
three-disk scattering system. We introduce a new numerical method for computing
resonances, which allows for going much further into the semiclassical limit.
As a consequence we are able to confirm the fractal Weyl law over a
correspondingly large range.
