We study the properties of the superdeformed (SD) bands of {sup 195}Pb and {sup 193}Hg by the cranked Hartree-Fock-Bogoliubov method. Our calculations reproduce the flat behavior of the dynamical moment of inertia of two of the SD bands of {sup 195}Pb measured recently. We discuss possible configuration assignments for the observed bands 3 and 4 of {sup 195}Pb. We also calculate the two interacting SD bands of {sup 193}Hg. Our analysis confirms the merit of density-dependent pairing forces as compared to seniority pairing interactions. {copyright} {ital 1997} {ital The American Physical Society}
