Paper Abstract

We modify the standard statistical model for precompound reactions (exciton model) by taking into account the correlations between fluctuating S-matrix elements with different total spin values. While angle-integrated cross-sections are not affected by our modification, differential cross-sections become asymmetric about 90 degree(s) c.m. This asymmetry weakens with time and with increasing complexity of the decaying nuclear system, but need not disappear even for the compound (thermalized) system. We present a comparison with data on double differential cross-sections in 184W(n,n') and 209Bi(n,n') inelastic scattering showing such an asymmetry.
