While our formal result can be considered as just a minor improvement compared with the known results obtained by popular KAM technique, we rather use more straightforward perturbation series construction to obtain explicit form for eigenvalues and eigenfunctions. To our surprise, the Rayleigh-Schrodinger series are directly convergent without the need of additional adjustments. This is the joint work with I. Kachkovski and L. Parnovski.
