The r-process paths predicted by several recent formulations for nuclear masses and fission barriers are compared. Three different compilations of nuclear masses were used in the calculations: empirical estimates derived on the basis of alpha and beta-decay energy systematics (Viola et. al., 1974), masses derived using the Seeger and Howard formula (1975) involving separation into a macroscopic liquid drop term and microscopic corrections; and masses obtained using the droplet model formula of Myers and Swiatecki (1969; 1974). Results indicate that the bulk of the r-process period responsible for the abundance peak at the atomic mass number 195 does not produce superheavy nuclei. The primary reason for the decrease in the maximum mass number achievable from that given by previous calculations is an increase in the magnitude of the surface asymmetry term in the newer mass formulas, resulting in lower fission barriers along the r-process path.
