Resumen:
In a complex scattering system with few open channels, say a quantum dot
with leads, the correlation properties of the poles of the scattering
matrix are most directly related to the internal dynamics of the system.
We may ask how to extract these properties from an analysis of cross
sections. In general this is very difficult, if we leave the domain of
isolated resonances. We propose to consider the cross correlation
function of two different elastic or total cross sections. For these we
can show numerically and to some extent also analytically a significant
dependence on the correlations between the scattering poles. The
difference between uncorrelated and strongly correlated poles is clearly
visible, even for strongly overlapping resonances.
