Measure of absorption in multistep compound processes
Description
The Moldauer-Simonius theorem, that relates the modulus of the determinant of the average, optical, S-matrix, to the average width and spacing of the compound nucleus resonances, is generalized to the multiclass resonances situation encountered in pre-equilibrium reactions. Corrections to the generalized M/S theorem are seen to be connected primarily to the width distribution of the widest doorway class. (Author)
Abstract (Portuguese)
O teorema de Moldauer-Simonius, que relaciona o modulo do determinante da matriz S otica media a largura media e ao espacamento das ressonancias de nucleo composto, e generalizado a situacao encontrada em reacoes de pre-equilibrio. Correcoes ao teorema M/S generalizado estao associadas primariamente a distribuicao de largura da classe 'doorway' mais larga. (Autor)Additional details
