The new, model-independent method to estimate simultaneously the level densities excited in the (n,γ) reaction and the radiative strength functions of dipole transitions is developed. The method can be applied for any nucleus and reaction followed by cascade γ-emission. It is just necessary to measure the intensities of two-step γ-cascades depopulating one or several high-excited states and determine the quanta ordering in the main portion of the observed cascades. The method provides a sufficiently narrow interval of most probable densities of levels with given Jπ and radiative strength functions of dipole transitions populating them.
