  • Using astochasticmodel for N compound—nucleusresonances coupledto thechannels,we calculatein the limit N—* theensembleaverageof theS-matrix (the “one-point function”),andof theproductof an S-matrixelementwith thecomplexconjugateof another,both takenat different energies(the “two-point function”). Using a generatingfunction involving both commutingand anticommutingintegrationvariables,we evaluate the ensembleaveragestrivially. The problem of carrying Out the remaining integrationsis solved with… CONTINUE READING
