Potential of present-day experiments for determining the parameters of the gamma decay of compound states of heavy nuclei in a model-independent way

Experimental data on two-step cascades initiated by thermal-neutron capture in ^184,186W and ^190,192Os nuclei are analyzed from the point of view of prospects for improving the reliability of a model-independent determination of the density of levels in a given interval of J ^π and the radiative strength functions for E1 and M1 transitions exciting these levels in the region E _exc≤B _n .
