Abstract
Theoretical investigations of the structure of the low-lying states of the nuclei with Z ≈ 100 play an important role in understanding the properties of nuclei belonging to the new region of the nuclide chart which are now available for the experimental study. We perform the calculations of the excitation energies and the wave functions of the low-lying states of the nuclei with Z ≈ 100. The quasiparticle-phonon model, which takes into account the interaction of quasiparticles with phonons of different multipolarities, is used as a basis for the calculations. The excitation energies and the quasiparticle-phonon structure of the low-lying states with excitation energies up to 1200 keV of the odd-neutron nuclei 245–251Cm, 249–255Cf, 249–259Fm, 253–259No and 257–261Rf are calculated. It is shown that the excitation of the phonons and the quasiparticle-phonon interaction play an important role in the description of the properties of the excited states of the nuclei with Z ≈ 100 with excitation energy exceeding 600 keV.
