Abstract
We derive a compact formula for the mean squared matrix element of a t wo-body force in the A-body space and its N-exciton subspaces. Applica tion to the spreading widths of symmetry breaking interactions shows t hat the contributions of rank one and rank two exciton operators are o f the same order of magnitude in typical compound nuclear reactions.
