Title in Portuguese
Fusão nucelar e secção de choque total de reação para o sistema 27Al + 16O
Keywords in Portuguese
Fusão nuclear
Abstract in Portuguese
Neste trabalho são apresentadas medidas das secções de choque de fusão nuclear para o sistema ANTPOT 27 Al + ANTPOT. 16 0,nas energias de bombardeio do feixe de ANTPOT 16 O de 45.6 MeV e 49 MeV. Também foram calculadas através do estudo do espalhamento elástico de ANTPOT 16 O por ANTPOT. 27 Al (modelo Óptico), as secções de choque de reação na faixa de energia de bombardeio de 30 MeV a 45.6 MeV. Na energia de bombardeio de 45.6 MeV, foi feito um estudo da contribuição de outros tipos de reações para a secção de choque total de reação. Neste esquema foi detetada experimentalmente a reação ANTPOT. 27 Al (ANTPOT. 16 O, C). Os dados da secção de choque de fusão nuclear foram comparados com o modelo de Glas e Mosel e foram obtidos valores do momento angular critico (l IND. Cr ). Contribuições de processos como emissão de pré-equilíbrio e fissão nuclear foram calculadas com o uso do código de evaporação Alice.
Title in English
Nuclear fusion and total reaction cross section for 27Al + 16O
Keywords in English
Nuclear fusion
Abstract in English
In this work we present cross-section measurements for nuclear fusion in the 27 Al + 16 O system, at 16 O bombarding energies of 45.6 MeV and 49 MeV. With the aid of the optical model the elastic scattering of 16 O by 27 Al was used to calculate reaction cross-section from 30 MeV to 45.6 MeV. At 45.6 MeV contributions by reaction mechanisms other than fusion were studied. The nuclear fusion cross-sections were compared with the model of Glas and Mosel and values of the critical angular momentum (l cr ) extracted at the above cited energies. Contributions by fusion and pre-equilibrium emission were calculated with the code "Alice".
