Para isso discutimos em detalhe o formalismo baseado no modelo de camadas extremo para tratar as taxas do processo de decaimento fraco não-mesônico. O potencial de transição para o processo com mudança de estranheza ('delta'S =1), 'lâmbda'nü' 'SETA'nü'nü', foi construído a partir de diversos modelos de troca de um méson incluindo, além da troca dos mésosns pseudoescalares ('pi', 'capa', 'eta') e dos mésons vetoriais ('rô', 'ômega', 'capa'*), uma nova contribução devido ao méson escalar-isoescalar 'sigma'. Apresentamos tmbém os resultados numéricos obtidos para a taxa não mesônica total 'gama IND. nm='gama IND.n' + 'gama IND. p' e para a razão 'gama IND. n'/'gama IND. p' no decaimento do 'INTPOT. 5 ANTIND. 'LÂMBDA' He'. Esses resultados comprovam que a influências do méson 'sigma' é significativa e vai na direção de aumentar a razão 'gama IND. n'/'gama IND. p' / In this work we investigate the influence of the exchange of a scalar-isoscalar sigma meson on some of the main observables in the nonmesonic hypernuclear weak decay. We discuss in detal the formalism based on the extreme shell model for the computation of the nonmesonic weak decay rates. The weak transition potential for the strangeness changing ('delta'S =1) process 'lâmbda'nü' 'SETA'nü'nü' is constructed based on several one-meson-exchange models, that include, beyond of the pseudoscalar ('pi', 'capa', 'eta') and the vector ('rô', 'ômega', 'capa'*) mesons, a ew contribution due to the scalar-isoscalar 'sigma' meson. We also present the numerical results obtained for the total nonmesonic rate, 'gama IND. nm='gama IND.n' + 'gama IND. p', and for the ration 'gama IND. n'/'gama IND. p' in the decay of 'INTPOT. 5 ANTIND. 'LÂMBDA' He'. We show that the influence of the 'sigma' meson is significant and goes in the direction of increasing the 'gama IND. n'/'gama IND. p'ratio.

Decaimento de ressonâncias gigantes em núcleos esféricos e deformados / Decay of giant resonances in spherical and deformed nuclei

Max de Oliveira Roos 21 June 2001 (has links)
O decaimento de ressonâncias gigantes (RG\'s) em núcleos tipicamente esféricos, ANTPOT.40 Ca, ANTPOT.90 Zr e ANTPOT.208 Pb, são interpretados em termos de suas larguras de escape nos processos direto e de pré-equilíbrio. Os cálculos são embasados na Teoria Estatística de Múltiplas Etapas de Núcleo Composto, de Feshbach, Kerman e Koonin (FKK). É feito um estudo comparativo, analítico e numérico, entre as aproximações FKK e de Oblozinsky, no contexto de densidade de níveis, no cálculo das larguras de damping e de escape. No caso das larguras de damping () não há diferença apreciável entre as referidas formulações no intervalo de energia estudado. Por outro lado, para as larguras de escape () podemos ter diferenças apreciáveis dependendo do núcleo, do tipo de núcleon emitido e da própria energia de excitação. A largura total das RG\'s, (= + ) , para algumas RG\' s nos núcleos mencionados acima, é comparada com dados experi-mentais e com outros cálculos teóricos, obtendo-se uma razoável concordância de resultados. No que se refere a núcleos deformados, apresentamos uma proposta teórica para o cálculo da largura de escape do decaimento direto de RG\' s. Consideramos um núcleo constituído de um coroço levemente deformado com simetria axial acoplado a um par partícula-buraco. O sistema formado decai, emitindo um núcleon, através do processo direto. / The decay of Giant Resonances (GR\'s) in typically spherical nuclei, 40Ca, 90Zr e 208Pb, are interpreted in terms of its escape widths in the direct and preequilibrium processes. The calculations are based in the Statistical MultiStep Compound theory of Feshbach, Kerman anel Koonin (FKK). It is made a comparative study, analytical and numeric, between the FKK and oI Oblozinsky approaches, in the level density context, for the calculations of the damping and escape widths. In the case of the damping widths () there is no appreciable difference among the mentioned formulations in the energy interval studied. On the other hand, for the escape widths () we can have significant differences depending on the nucleus, of the type of emitted nucleon and of the excitation energy. The total wiedth (= + ), for some GR´s of the nuclei mentioned above, it is compared with experimental data and with other theoretical calculations, being obtained a reasonable agreement among the results. For deformed nuclei, we presented a theorctical proposal for the calculation of the escape width in the direet decay of a given GR. We considered a nucleus constituted of a core softly deformed with axial symmetry coupled to a pair particle-hole. The formed system decay emitting a nucleon through direct process
