Query: Distribution of proper delay times in quantum chaotic scattering: A
  crossover from ideal to weak coupling   The probability distribution of the proper delay times during scattering on a
chaotic system is derived in the framework of the random matrix approach and
the supersymmetry method. The result obtained is valid for an arbitrary number
of scattering channels as well as arbitrary coupling to the energy continuum.
The case of statistically equivalent channels is studied in detail. In
particular, the semiclassical limit of infinite number of weak channels is paid
appreciable attention.
