N2 - Effective single-particle potentials obtained from the established nonrelativistic nuclear energy density functional approach are incorporated into the microscopic-macroscopic method to calculate the ground-state shell corrections, mass excesses, and Qα values for heaviest nuclei. The low-lying one-quasiparticle states are studied in the isotonic chains with neutron numbers N=175, 176, and 177. The isomeric states are discussed in the odd isotopes. The possible α-decay chains of nuclei 119295 and 120295,297 are analyzed and compared with the available experimental data. The termination of the α-decay chains by spontaneous fission is analyzed. The production cross sections are calculated for superheavy nuclei with 112≤Z≤120 in the actinide-based complete fusion reactions with projectiles Ca48, Ti48,50, Cr54, Fe58, and Ni64.
