Abstract: To further study the 'pygmy' resonance phenomena in the photon strength function, we reanalyzed the two-step cascade data for the target nucleus $^{197}$Au using the Dubna group approach. The range of obtained values allows for meaningful conclusions: the level density at low excitation energy shows a step-like behavior/ the electric dipole photon strength function has a broad maximum around $E_{\gamma}=5$ MeV and is not typical of a 'pygmy' resonance/ the level density below $B_{n}$ also demonstrates step-like behavior.
