Low-lying excited states of the odd-proton nuclei with Z ≈ 100

Background: Theoretical investigations of the structure of the low-lying states of nuclei with Z approximate to 100 play an important role in understanding the properties of nuclei belonging to the new region of the nuclide chart which is available now for experimental study. Purpose: We perform the calculations of the excitation energies and wave functions of the low-lying states of nuclei with Z approximate to 100. Methods: The quasiparticle-phonon model, which takes into account an interaction of the quasiparticles and phonons of different multipolarities, is used as a basis for the calculations. Results: The excitation energies and the quasiparticle-phonon structure of the low-lying states with excitation energies up to 1200 keV of the odd-proton nuclei Bk239-251, Es243-255, Md247-257, Lr-253,Lr-255, and (261,263)Db are calculated. Conclusions: It is shown that starting from 600 keV 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 nuclei with Z approximate to 100.
