The independent analysis of the published data on the intensities of the primary gamma-quanta following resonance neutron capture in $^{236}U$ has been performed. Distribution of these intensities about the mean value was approximated in different energy intervals of the primary gamma-transitions and neutrons. Extrapolation of the obtained functions to the zero registration threshold of the primary gamma-transition intensity allowed us to estimate (independently on the other experimental methods) expected level number of both parities for spin values J=1/2, 3/2 and sum of radiative widths for both electric and magnetic dipole gamma-transitions to levels with excitation energy up to $\approx 2.3$ MeV. 17 pages, 8 figures
