Abstract In this paper, we derive the higher order Hamiltonian of the three-wave interaction fermion model II by the Neumann expansion and find it physically interesting as related to the pairing process of the high Tc super-conductivity. The eigenvalues and Bethe-ansatz equation are also obtained by the quantum inverse scattering method.
