We cons.der a three-electron s.s.em in the Impurity hubbard model with a coupling between neares.-neighbors. Our res.arch aim cons.s.s.of s.udying the s.ructure of es.ential s.ectrum and dis.rete s.ectra of the energy operator of three-electron s.s.ems.in the impurity hubbard model in the quartet s.ate of the s.s.em in a v-dimens.onal lattice. We have reduced the s.udy of the s.ectrum of the three-electron quartet s.ate operator in the impurity hubbard model to the s.udy of the s.ectrum of a s.mpler operator. We proved the es.ential s.ectra of the three-electron s.s.ems.in the Impurity hubbard model in the quartet s.ate is.the union of no more than s.x s.gments. and the dis.rete s.ectrum of the s.s.em is.cons.s.s.of no more than four eigenvalues.
