Abstract in Portuguese
Através de um hamiltoniano efetivo baseado no tratamento de NAMBU POT.90 para o BCS, no qual incluímos além do emparelhamento monopolar o emparelhamento quadrupolar, discutimos a relação entre esse modelo e o modelo de bósons interagentes. Uma aplicação e feita a cadeia o (6) do IBM, que corresponde ao limite GAMA-instável do modelo de bohr. As dificuldades encontradas e uma possível generalização para o modelo são discutidas.

Abstract in English
The nambu mechanism for BCS theory is extended with inclusion of quadrupole pairing in adition to the usual monopole pairing. An effective Hamiltonian is constructed and its relation to the IBM is discussed. We discussed the faced difficulties and a possible generalization of the model.
