Abstract
The fluctuations and correlations of matrix elements of cross sections are investigated in open systems that are chaotic in the classical limit. The f orm of the correlation functions is discussed within a statistical analysis and tested in calculations for a damped quantum kicked rotator. We briefly comment on the modifications expected for systems with slowly decaying cor relations, a typical feature in mixed phase spaces. (C) 2001 Elsevier Scien ce B.V. All rights reserved.
