Radiative strength functions of El-and Ml-transitions from ground states of doubly even deformed nuclei to states near the neutron binding energy B, arc calculated within the quasiparticle-phonon nuclear model. The wave functions of excited states include one-and two-phonon components. The calculations were made with the Pauli principle being or not included in the two-phonon components of the wave functions. It is shown that the radiative El-and M 1-strength functions as well as the widths of giant dipole resonances in deformed nuclei are slightly influenced by the two-phonon components of the wave functions and they can be calculated in the RPA. The kE1-and kMl-values are calculated for some deformed nuclei of the rare-earth and actinide region. The calculated values of kE~ are 1.5-2 times larger and the values of k~t ~ are somewhat less than the average values obtained in [14] from the analysis of available experimental data.
