  The new, model-independent method to estimate simultaneously the level
densities excited in the (n,gamma) reaction and the radiative strength
functions of dipole transitions is developed. The method can be applied for any
nucleus and reaction followed by cascade gamma-emission. It is just necessary
to measure the intensities of two-step gamma-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 J,pi and radiative
strength functions of dipole transitions populating them.
