Methods and related parameters for modelling gamma-ray cascades due to the gamma-transitions in highly excited nuclei will be reviewed. Analytical expressions for the photon strength functions (PSF) will be done with allowance for low-energy enhancement due to the nuclear structure effects (presence of low-energy resonance). The models and formulae previously recommended for the PSF will be updated, additionally tested and validated. Recommended sets and systematics of the parameters for PSF’s calculations will be prepared. Computer code for PSF calculations within recommended models will be prepared and adopted for the use in the different codes for nuclear reaction calculations. Applications of the results to the gamma transitions in different nuclear processes (neutron induced nuclear reactions, isomeric ratios of primary fission fragments) will be considered.
Final expressions for the average description of gamma-transitions will be tested and validated with the use of modern experimental data.
