Developed by authors, the methods of calculation of mixing states of odd nuclei amplitude where among the component of multiplets of the excited states is observed with the same quantum characteristics as well as in the main state and is used for the determination of amplitudes of mixing states in nuclei 23Na, 25Mg, 27Al, 41K, 51V, 55Mn, 59Co, 63Cu, 65Cu, 93Nb. Quantitative assessment of the influence of the mixing states to calculate cross-section of the direct inelastic scattering of nucleons was obtained.
