Some problems in determining level density and radiative strength functions in light and near-magic nuclei

The values of some functional dependencies of level density and radiative strength functions that reproduce the experimental intensities of the two-step gamma-cascades to the ground and first excited states of 28Al have been determined. It was shown that the assumption about independence of the dipole cascade transitions radiative strength functions on energy of decaying level leads to rather essential error in observation of both level density and radiative strength functions.
