  The closed-form expressions for the photon strength functions (PSF) are
tested using the gamma-decay data of OSLO group. The theoretical calculations
are performed for the Lorentzian models of PSF for electric and magnetic dipole
gamma-rays. The criteria of minimum of least-square value as well as the
root-mean-square deviation factor are used. It is shown that a rather good
agreement is obtained within the Simple Modified Lorentzian model for E1 PSF
modelling.
