The possibility of measuring the nuclear correlation width via atomic electron spectroscopy

The correlation width GAMMA of the autocorrelation function of the nuclear scattering matrix, usually determined through the analysis of Ericson fluctuations of nuclear cross sections, manifests itself also in the spectra of atomic electrons ejected coherently prior to and after nuclear scattering. We propose to determine GAMMA from a coincidence measurement between nuclear reaction products and atomic electrons, a method which does not require good energy resolution of the incident beam, and which would make it possible to measure GAMMA in a range of values not accessible before.
