The properties of strongly deformed transuranium elements are investigated on the basis of the superfluid model of the nucleus. Some insignificant modifications are introduced in Nilsson's schemes by employing the experimental data and taking into account the effect of superfluidity. The pairing energies are computed and the following values for the coupling constants have been obtained: G/sub n/ = O.O2Oh omicron /sub 0/, G/sub p/ = 0.022h omicron / sup 0/0. Single-particle excitation spectra are calculated for odd mass nuclei, the calculated level density being about twice as large as that predicted by the Nilsson scheme. Single-particle excitations in even-even nuclei are computed, and in all calculated spectra for even-even nuclei (Th/sup 2//sup 3//sup 2/, U/ sup 2//sup 3//sup 4/, Pu/sup 2//sup 3//sup 8/, Pu/sup 2//sup 4//sup 0/, Pu/sup 2// sup 4//sup 2/, Cm/sup 2//sup 4//sup 6/, and Cf/sup 2//sup 4//sup 8/) the lowest levels were found to be the 1/sup -/ levels which lie below 1 Mev. Corrections to beta - and gamma -transitions due to superfluidity of the ground and excited states are computed. The results obtained are self-consistent: correct values for pair energies and levels of even and odd nuclei are obtained for the same values of G, whereas variation of G by 30--40% leads to a pronounced deviation from the experimental data.
