    "abstract": "The calculation of the spreading width of a compound nuclear reaction caused\nby a symmetry breaking $K$-body force acting in an $A$-body system ($K \u003c\u003c A$,\nusually $K=2$) involves the determination of the local average square matrix\nelement in $A$-body space. This problem is reduced to finding the global mean\nsquare matrix element $v^2$ in $K$-body space. The result is a compact formula\nfor the spreading width which contains $v^2$ as an input. Our method is based\non the dilute gas approximation for excitons close to the Fermi edge. The\nrelative strength of the contributions of operators with different exciton rank\nas well as the connection between the energy dependence of the spreading width\nand the body rank of the underlying interaction are established.",
