Abstract
The Ericson energy autocorrelation function c( ε) has a purely lorentzian shape only in the limit of infinitely many open channels, and the Heidelberg group has recently explicitly evaluated corrections to it through the first few orders in 1 TrP . We investigate the influence of these corrections on the spectral density method for analyzing fluctuation data, and estimate it to be small but not negligible in realistic situations. However, the form of these non-lorentzian corrections suggests the presence of a range of correlation widths, and we conjecture that the concept of a distribution of total widths for non-overlapping resonances may best be generalized, for overlapping ones, to a distribution of correlation widths.
