'Sum rules' for preequilibrium reactions

Creators

Description

Evidence that suggests a correct relationship between the optical transmission matrix, P, and the several correlation widths, gamma sub(n), found in nsmission matrix, P, and the several correlation widths, n, found in multistep compound (preequilibrium) nuclear reactions, is presented. A second sum rule is also derived within the shell model approach to nuclear reactions. Indications of the potential usefulness of the sum rules in preequilibrium studies are given. (Author)

Abstract (Portuguese)

Apresentam-se evidencias que sugerem um relacionamento correto entre a matriz de transmissao otica, P, e as varias larguras de correlacao, gamma sub(n), encontradas nas reacoes nucleares (pre-equilibrio) compostas de multipassos. Deriva-se, tambem, uma segunda regra de soma dentro da abordagem do modelo de camadas para reacoes nucleares. Dao-se indicacoes da utilidade do potencial das regras de soma em estudos de pre-equilibrio. (Autor)
