Transfer reactions of heavy ions with /sup 248/Cm targets are evaluated for their usefulness in producing unknown neutron-rich actinide nuclides. Cross sections for the production of nuclides in the region 91< or =Z< or =100 were determined radiochemically from bombardments with /sup 18/O, /sup 86/Kr, and /sup 136/Xe ions. The systematic trends in the cross sections for these reactions can be understood in terms of the Coulomb potential and the stabilizing effect of the reaction Q values, which tend to favor the production of nuclei with Z>Z/sub target/ with low excitation energies. Extrapolation of the product yields into unknown regions of charge and mass indicates that the use of heavy-ion transfer reactions to produce new neutron-rich above-target species is limited. Substantial production of unknown neutron-rich below-target species is expected in reactions with heavy projectiles like /sup 136/Xe and /sup 238/U.
